Skinner has been on the block for months and the Canes were quite public about it. Not being "properly shopped around" doesn't fly. It's the interested parties that determine how much a player is worth, not Waddell's skills as a salesman. If you want to criticize the decision to trade him for that price in lieu of bringing him back and trading him later, knee jerk, that's potentially a fair point. However, the value wasn't going to get better in the short-term. It was what it was. That's all the market would bear.
