He's 29 years old, has one more year of a $3m contract, has 5 goals and 5 assists so far and can be a pretty solid two way center. Given that we are bound to trade away so much salary at the trade deadline anyways, picking him up wouldn't put us back financially or cap-wise.
Even though he's a center and it looks like we will have some problems on the wings next season, it never hurts to have another centerman, especially since I believe that we trade Goc at the deadline, and who knows what will happen to Weiss.
He used to fool lots of goalies when they weren't accustomed to facing the Forsberg deke. I think everyone has him scouted now. He's a got a quick release which also ups the probability of a scoring chance. So, Jokinen's got the quick shot, the Forsberg drag move and the backhand (I could be wrong about his backhand). He's a good shootout player but not a specialist, IMO.
