Of those available to sign, Duhon or Anthony Carter
would likely be the best options. Both are pretty seriously limited though. Otherwise, BC may try to get a veteran PG back when making a trade involving TJ. Most of the proposed deals I've heard involve at least one other player from our end, usually Rasho or Joey, or draft picks. So if we're giving up two players, or a player and a draft pick, we would likely be getting a couple back. (Although given that the Clips are the most popular rumour, Im not sure we'd want a point guard back) And even if BC grabs a 2nd rounder via a trade, there arent many 4 year savvy point guards in this years class, and the Raps sure as hell arent going with a pg at 17.
Basically, whatever happens, Jose will be expected to play 35+ next year.
