Clague for sure--though let's not forget his injury. And right now our left side is relatively empty.
JAD is only 20 and a 2nd year pro, he SHOULD push for a spot, but it's not the end of the world if he doesn't lock it down until the following year.
Grundstrom is a good one I relatively forgot about, this is probably his make or break year here.
I guess just looking at the roster at the end of this year--
Iafallo-Kopitar-Brown
X-Vilardi-X
X-Kempe-X
Lizotte-Moore-Wagner
Fill in the blanks with any number of Prokhorkin, Amadio, Carter, Frk, JAD, Grundstrom, and whoever else pops up.
X-Doughty
X-Walker
X-Roy
Where X is any number of the rumored Nikita Nesterov, another UFA, Bjornfot, Clague, Anderson, etc.
I did this quickly so I'm sure I overlooked something/someone, feel free to correct me to shut me up, but that looks like easily 4-6 total rookies counting healthy scratches...so I'm counting on Clague and Grundstrom for sure but also some camp surprises (Fagemo, for example?).
