I've felt that Thomas Greiss was underrated for years.  When I started at Razzball, he was battling Halak for playing time and should have received more than he did.  Last season, when I was fully buying in, he was a mess.  This year, his value was so low that he was a nice gamble and he paid off handsomely.  Greiss had a 31 save shutout on Thursday beating Columbus 3-0.  Greiss is pushing a .930 save percentage and it's deserved; he's third in the league in goals saved about expectation.  The bad news is that his teammate is #2 in that category.  Look, Greiss isn't going to get the majority of starts, right around half of the Isles remaining games.  However, those starts are going to be extremely valuable.  He's only owned in 23% of leagues right now which is far too low.  That reason alone is why I'm starting this post with Greiss.  I've been saying for over a month that he should be owned in all formats, but if you're lucky enough for him to still be on the wire, go and get him.  Let's take a look at what else happened over the last two nights:

The Bruins split up their first line recently and there's been one massive winner: Danton Heinen.  Heinen had a great rookie season in 2017-18 with 47 points in 77 games.  He's struggled mightily this season but Heinen has taken off since moving onto a line with Marchand and Bergeron.  Heinen had a goal and two assists with three shots against the Blackhawks on Tuesday.  That gives him three goals and three assists in the past four games, with at least three shots on goal in every game.  If you're in a 16+ teamer, Heinen should be owned no matter the format.  Even in 12'ers, I am good with holding onto Heinen while he's hot and the Bruins have three games in four nights starting on Friday.  At the least, he's moved up to elite streamer status as he's as hot of a schmotato as they come.  Let's take a look at what else happened over the last two nights:
It was only a matter of time until Vladimir Tarasenko picked up his play.  Tarasenko had four goals over the weekend, including a hat trick on Sunday, in two games against the Predators.  That gives him an eight game point streak to get to 22+19 on the season.  Obviously that's still disappointing, but there's time for him to salvage the season.  Hell, the Blues are even in a playoff spot now because of how bad the Western Conference is.  Look for them to make some additions at the deadline because of all of the moves they made in the summer.  Missing the playoffs would be a major disappointment, and creating depth for the lineup would help things out for Tarasenko.  The buy low window is probably closed but there's a strong chance that he's a top 30 player the rest of the way.  Let's take a look at what else happened over the weekend:
It's no secret that the Ducks are a mess right now.  I said in a post last week that they're the worst team in the league at the moment, but last night's game took the cake.  Getting shutout by the Senators is as low as it gets.  Sure, Anders Nilsson played great stopping 45 shots, but a lot of them were low quality like the team taking them.  This isn't a post about Nilsson, he's barely usable.  This is a reminder that you should stream against the Ducks every time you get.  Anaheim plays against plenty of bad teams this month (Vancouver 2x, Edmonton, Chicago) yet I still wouldn't hesitate to use any of their goaltenders.  Take advantage of the Ducks every opportunity that you get.  Let's take a look at what else happened over the last two nights:
Patrice Bergeron has had an excellent career to this point, one that gives him a chance at making the Hall of Fame one day if he ages well.  To this point, we've seen no signs of him slowing down.  That continued on Tuesday as Bergeron scored two goals in his 1000th career NHL game.  He became the fifth Bruin to reach that mark, and he'll be 3rd all-time early next season behind Bourque and Bucyk.  On a per-game basis, this has been the best season of his career.  He has 18+28 in 37 games with an elite shot rate.  This is his eighth straight season with a Corsi over 56%.  Bergeron is arguably the best defensive center in the game who is good enough to dominate the other team's top players on a nightly basis.  His prowess is what gives the Bruins a chance to upset someone, presumably Toronto, in the first round of the playoffs.  I wouldn't be selling high if I owned him; the first line is so damn good that very few teams have a chance against them.  Let Bergeron continue to provide great value to your team.  Here's what else happened on a busy Tuesday night:
In my Monday post, I called Frank Vatrano the best streamer of the night.  As simple as my rationale was, getting to play with Barkov does wonders for anyone.  Vatrano has been playing well lately, but the jump to the first line helps tremendously, and he showed how on Monday.  Vatrano scored a goal and dished three assists in the 6-2 win over the Sharks, putting five shots on goal in the process.  Normally, I'd say go get Vatrano right now to see what happens.  There's definitely upside going forward.  The problem is that the Panthers don't play again until next Friday.  For those in roto leagues, I would grab Vatrano now and stash him on your bench.  In head to head leagues, I would wait until the middle of next week unless a spot opens up on your roster due to someone going on injured reserve.  However, I definitely want Vatrano for the back-to-back next weekend, so don't wait until last minute so you avoid somebody else sniping you on him.  There's a real chance Vatrano, who was a prolific AHL goal scorer and showed upside before in Boston, could become a hold for the rest of the season.  Let's take a look at what else happened this week:
It feels like forever ago that Tomas Hertl took the league by storm as a rookie.  He's shown signs of promise since, but never really put it together.  Until.  Hertl had a hat trick on Tuesday to lead the Sharks over the Penguins.  That brings him up to 19+22 in 43 games, both numbers rapidly approaching career highs in mid-January.  He is providing no penalty minutes and a below average shot rate which caps his long term ceiling, but he looks to be a guy who is a fringe top 100 player for the next few seasons.  I would say if I had to say where I rank him next year, my guess is just outside the top 100 just because the downside is much higher for a guy whose sole value is coming from points and not the side categories.  Let's take a look at what else happened on Tuesday night:
It was less than a week ago that James van Riemsdyk was placed on the fourth line for the Flyers and Scott Gordon had a private meeting with him.  Since then, JVR has taken off, with a monster game coming on Monday.  He scored a hat trick to give him 5+2 in his last 3 games.  Look, we know how good of a player JVR can be; he's been a top 100 player the past few seasons.  However, he only has two games the rest of the week, and then he doesn't have a game for all of next week with the Flyers on a bye week.  Therefore, I wouldn't be holding him right now.  I'd be willing to stream him on Wednesday and Saturday, but I'd cut bait then.  However, with a very heavy schedule starting 1/28, including a lot of bad teams, I would look to grab JVR at the All-Star break to get three games in four nights after that break.  Then, we see how he does in those three games, and proceed from there.  Here's a look at what else happened on Monday night:
The Penguins have been on quite a tear lately, and it's not just their All-Stars.  Over the weekend, Jake Guentzel destroyed the Ducks and Kings.  In the Penguins comeback against the Ducks, Guentzel had a hat trick on seven shots with two penalty minutes, before scoring two more goals on six shots against the Kings.  That brings Guentzel to 23 goals, which is already a career high.  The shot rate has taken a big jump as well, although we can't expect him to shoot 19% all season.  Regardless, Guentzel has settled into being a top 100 player who is a clear hold in all formats.  As long as he continues to play with Crosby, things will be just fine.  Let's take a look at what else happened over the weekend:
We found another goalie out of nowhere!  Jordan Binnington was great in his second start on Thursday, allowing one goal on 29 shots in the 4-1 win over over Canadiens.  He's been strong in the AHL the last two seasons, and with how bad their other goalies have been, Binnington deserves a chance.  Obviously it could collapse at any time, and the Blues' schedule in January is very road heavy.  On the other side, there a lot of good matchups over the next two weeks for Binnington.  I wouldn't go out of my way in shallow leagues to own him, but Binnington could be a solid streamer with upside for more, especially before the All-Star Break with the Sens, Kings, and Ducks in a row.  Let's take a look at what else happened over the last two nights:
