I want him. When he plays, its over ppg. and he's injured put him to IR and grab a free hot hand player to ride until fors comes back.
Having said that, I opted to not take him on most my teams as im already rolling 3 to 4 stud centers and can't justify there losses.
So the long answer is, assess your team and see who you could get rid of without hurting you too bad. I opted to lose Downie in one league and Ott in another. Both leagues count PIMs and Hits. Ott for Fors is a no brainer. However, you have to keep in mind the 90% chance Forsberg goes down for lengthy stretches. In that case, is there decent options currently in FA if Ott gets scooped up? If so, fire away for Forsberg and love the late xmas gift from the hockey gods.
