Birth certificate says "Isaiah Thomas", but his game say "Alan Iverson", except more efficient. This dude is a nasty basketball player. I think the only reason he's undervalued is the height. That's it. He plays like a bigger player, similar to how Pedroia swings like a bigger hitter. He was impressive tonight, but go look at his game logs from last year. This is apparently what Isaiah Thomas* already did and can do on the regular. Except even a little better.
I think Ainge sneakily got the first part of a future Big Three or Four or Five. And if Smart develops slightly more in the direction of Wade than Tony Allen, that'd be two starting parts already in place. The backcourt would be all set into the 2020's, the remaining multitude of assets all for conversion into a couple frontcourt stars. Plausible reason for excitement, yay.
*He needs a nickname good enough to make us forget he's named Isaiah Thomas.
