To Jose's defense (and I'm not trying to be a Jose apologist all over these boards), he's the only active true PG right now. He's conserving his energy because all of a sudden he's playing 40+ minutes a night.
When Juan Dixon is the only guy spotting you off the bench, you need to save some gas for the 4th quarter.
To further back up Jose (I swear, I'm not related to him in any way), he's also only a 3rd year player.
I feel TJ has a lot of growing left to do, and has improved a lot in a season with us. Yet, he actually has more NBA experience than Jose! So if TJ gets the his 'decision making will improve in time' mulligan, then I'll grant Jose a 'he will know when to pick his spots and attack the defense' credit as well.
