He's already played two seasons in Austin. I am not so sure that him playing another 20-25 games up there at the beginning of the season are going to bring him along that much further than the 94 games he's already played. If no one is injured, and he's not getting playing time because he's in a suit behind the bench, then I'm all for shuttling him back and forth to Austin, some. But, given so many of our guys are 30+, I hope that we get them early rest days/DNPs, and I do not hope for, but fully expect injuries.
He's also not 21. He's an older, hopefully, more mature dude. I hope the opposite of you. I hope they find lots of opportunities to begin working him hard into the big Spurs, if they can. I want Tim, Manu, Tony, Boban, and maybe Patty (if his shoulder still is requiring any rest), to be rotating (not a cuff pun) in and out of suits whenever possible, just as a preventative. Bonner, too, for age and skill/depth reasons, all. God forbid an injury, and I think both Anderson and Simmons will both be suited (in uniform-not Barney Stinson-style) up many if not most nights?
Maybe I'm wrong, but I think he would learn a lot quicker in this situation. He has come a long way, obviously, playing for the Spurs-Austin, but after a couple of years, I would imagine that learning curve begins to flatten out a little, and you get some point of diminishing return. Like bacterial growth. Not exponential out to infinity, but a plateau. Probably learns more up here in a first year than down there for a third?
We've got several new pieces. They've all got to play a little to get acclimated with each other. It would seem you really want to do that early in the season, not late. When they screw up early, the vets can save their asses.
If Jimmer stays, or the guy that replaces him is not a Spurs-Austin guy (maybe even if he is, depending upon tenure), Jimmer or that dude may benefit the most from getting playing time in Austin just to learn the system a little bit. I don't know if Jimmer or McCallum would be sent, as they may see it as an affront. But, Daye was sent, and he was a 5 year vet, so it's not out of the question, I guess.
Maybe he ends up not being ready for the big leagues, but I hope he's good enough to get early and often burn, to allow Manu to rest as much as possible.
