What's with the desire to trade Kemba because we trade for Collins and need to sign him long term?
The team is staying under the luxury tax this year for the express purpose of going over the luxury tax for the foreseeable future. Wyc said he would pay the tax for a contender and adding an excellent talent like Collins means the team is a contender.
You don't remove an All-Star/All-NBA worthy talent like Kemba after trading for Collins. The point of acquiring Collins is to add him to the core of Kemba, the Jays, and Smart, not to replace one of them.
Wyc has gobs and gobs of money. The fans will be back in attendance and the Celtics will return to unreal profit margins. Let Wyc pay the tax. Keep all the top notch talent. Don't water it down by trading Kemba for parts. That, IMO, wouldn't be a very intelligent move.
