Loading up on minutes for only 10 or even 8 players is fine for playoffs but in the grind of a full season best to play 12 guys a game (and alternate last 3). Have to keep guys feeling fresh and not over fatigued. Pushing guys too far is easy way to get injuries and lower efficiency. On top of that the locker room could suffer. If you are busting your butt in practice and never get playing time you may lose hope with the team and stop practicing with effort thus dragging down the team. If a guy has a great practice he deserves a few minutes at least once a week. Remember this is their lively hood if they don't get some on the court time they lose value. If you mess with any man's earnings there will be a lot of anemostity and tension with the team. This is why guys like Bass got minutes last year. Great guy, very good in practice. He needed to get minutes in this contract year to stay a great guy and keep good team morale. You have to keep in mind these guys care and want to play. If you take away playing time they stop caring and trying, some even ask for a trade.
See, this is where I totally disagree. I get the season is long, but in what world is a 10 man rotation going to wear down as the season goes on? In the scenario I laid out in the original post, no one played more than 32 mpg. In a 10 man rotation, no one would likely even crack 30.
I think some people get too fixated on San Antonio. They play an extended rotation for two reasons: they're old and they have the talent to do it and still win a ton of games. We aren't old; there's no reason players in their 20s can't play 28-32 mpg with no ill effects. I get the Celtic fan base is somewhat traumatized still from Doc playing Ray and PP 36 mpg+, but this isn't the case here.
I also don't buy this locker room argument. I get how some players would be peeved if Stevens went with a 7-8 player rotation all season and gave no one a chance. But Stevens will likely go 9-10 deep all year. I also get that if this was the Big Three Era and we had some promising young guys who would never supplant our Hall of Famers, but still deserved to showcase their talents. But we have no superstars, so if a given player can't crack the top 9-10 spots on this team, quite frankly he shouldn't get PT and has no reason to complain about this.
And to D Dub and others of the mind that we play the likes of Zeller and Rozier 4-5 mpg, I sincerely ask this question: is it really worth doing that when someone like Smart or Sully could just play a few more minutes? Meaning, how much does 4-5 mpg really do to help a player develop and/or increase their value.
