Where are the Manu Defenders who were saying that Manu can play 35+minutes a game? Pop played him 37, 35 and 35 minutes in three straight games and that made him dead tired in the Nets game and now miss three games.
Manu is an awesome player, but he should never average more than 30 minutes per game. If you play him any more than that, he can't last an NBA season and his career is going to be shortened.
Best case scenario is bringing him off the bench for something like 28 minutes a night. That way he can play an entire NBA season and it will ensure that he'll still be able to walk by the time his contract is over. At this right, he's seriously setting himself up for trouble.
When he comes back, Pop must limit his minutes. From now to the end of the season, Manu has to rest up. If he doesn't, he's not going to be good enough in the playoffs for the Spurs to do anything.
This offseason, I'd really consider making it known that Manu is going back to the bench and going out and finding a starter. Manu's not going to make it at this rate.
