We're definently a playoff team with Vince. If, say, VC would have a season ending injury right now (three knocks on the desk...), then we would probably be back in the cellar again.
We're not a legit contender anyway, like Henacy pointed out, until we can fill in some holes. But there really isn't much of an option out there right now for an athletic big man who can defend. There aren't many anyway, and those that are good enough won't be traded so easily. The only two players I can think about getting that are good enough for us, but won't need to be traded for one of the big three in return, is Reggie Evans and (maybe)Stromile Swift. I'm not so sold on Swift being that good, anyways.
