surprised the oilers or any team for that matter haven't taken a flyer on Wisniewski. I still don't get why he was bought out. are there long term issues from his injury?
I don't think the buyout reflects poorly on him or his career prospects going forward. IMO, he was caught in a numbers game in Carolina. Can't play him in the top 4 because you'd be stifling the development of a younger player like Pesce or Slavin. At the same time, it's a waste of money to play him on the third pair - and at the same time, you're not sure about his knee.
Also, realize that Carolina has to have somebody to meet the 40/70 requirement for the expansion draft - otherwise they'd have to expose Faulk since he's the only eligible player under contract when it happens. Considering they likely didn't have plans to extend or re-sign Wiz, why not cut him now and let him get a chance with another team.
A lot of factors conspiring together led to that move, IMO. I'm not trying to prop up Wiz or anything, I'm not like a big fan of his, I can't even claim to have seen the 47 seconds he played for my team. I just think there were much different circumstances here than your typical buyout.
