Nerlens!! Could be more than a stopgap if everything works out. He's only 25 and has a lot of defensive potential
It's certainly an option if the Celtics aren't willing to part ways with Smart in a Capella deal. At some point Danny Ainge needs to put pressure on CBS to tweak the offense. In a perfect world, the combo of Kemba, Brown, Hayward, and Tatum would be able to score at a high level while on the court together. Capella is obviously a much better rim runner than Noel, but I'd much prefer to have Smart when the playoffs arrive. Either way it would be nice to have an efficient offense that doesn't rely on a floor stretching big man.
Ainge could always pursue two veterans with different styles. Here's some other names:
Dewayne Dedmon - Would be ideal as a stopgap. Concerned that someone will pay more than the Celtics can afford.
Frank Kamisky - Would be great for floor spacing in a 15-20 MPG role. Major liability on defense, especially when the playoffs arrive.
Ed Davis - Excellent rebounder and solid defender.
Noah Vonleh - Another good rebounder and he's shown improvement with the 3 point shot
As I mentioned, Ainge might end up signing a couple of players to fill the Center spot. There's also the possibility of other trades once the free agent period is over with. Maybe he moves a rookie, future draft pick, and filler for a veteran big man.
