Buy Low:
Jose Theodore - Florida Panthers
Maybe Dale Tallon had a point this off-season. He turned over the majority of the line-up, bringing in a bunch of role players - one being Jose Theodore to serve as a starter while Jakub Markstrom continued to develop. He's already got 10 wins and has a nice .924 SV%. If you take a close look at his recent numbers, he's actually lacking respect as a pretty good option in goal.
Fedor Tyutin - Columbus Blue Jackets
One of the many slow starters on the Jackets team this season, Fedor now has a point in 5 out of his last 6 games. He's playing alongside James Wisniewski on the first power play unit is averaging nearly 25 minutes a game. The Jackets aren't getting any worse (right?), see if you can get him as part of a throw-in.
Michael Grabner - Florida Panthers
The 34-goal scorer of a season ago is starting to heat up along with other Panthers - but he's proven in the past he's got great upside. Now I'm not sure if teams would be willing to part with a player who scored 34 goals last season, but throw a bone at a GM and see what happens.
Sell High:
Brian Elliot - St. Louis Blues
The key to finding a good "sell high" player is when a player is overt performing, playing better than usual. What makes this even more of a sell situation is that Jaroslav Halak is still a member of the St. Louis Blues. Lets face it, you claimed Elliot off waivers and he's done great things for your fantasy team - start shopping him around now while he's still at his peak.
Marc-Edouard Vlasic - San Jose Sharks
There is streaky, and then there is Marc-Edouard Vlasic. He scores his points in bunches in his last 8 games played he's only got on the score sheet twice. But the two times he did, he made it count with 7 points in those two games. I'm convinced there won't be many more 4 point nights for Vlasic.
Chris Kelly - Boston Bruins
He's tallied up 11 points in his last 12 games, the career third line center is enjoying a great streak in his career. He's put up good numbers but nothing exceptional. He's not getting any power play minutes. Shop him around and see if you can get yourself a top-6 forward that gets time on the PP.
