As much as the assets that Columbus got back in the trade are not spectacular, you can't forget that they were able to shed that enormous contract. As good as Nash is, they were not getting $7.5 million in value out of him on the ice, he's not that young anymore and there are a lot of years left. So you have to figure there's value in getting out of that equation.
IMO, a team/market like Columbus is not going to be successful trying to build a team around one player with such a high percentage of their payroll in him. They have to build the way Nashville did, with depth, consistency and work ethic, and expect to do some rebuilding more often than the bigger market teams.
