If they re-sign Grant, it will take some serious tap-dancing to stay under the Lux Tax next season, let alone wait for a contender.
Trade Hart for another ending contract? (But then basically, we have let Hart go for nothing)
Trade Nurk for an ending contract and then try to sign someone to play Center that makes a lot less? Possible, but what option out there does that and makes them better?
They are just paying too much for the players they have for the results they are getting, and it is going to be tough to significantly change that. The one hope is that Sharpe blows up while he is on his rookie contract.
