You guys are missing the point. The problem with playing Jack too many minutes isn't that he's 32. The problem is that he's terrible.
Here here. Jack has played about as well as he's ever played at times this year, but he's still not a very good player. It's hard to play Jarrett Jack 35 mpg and expect to win more games than you lose. Especially when Shane Larkin is your back up.
TP to you two.
And Tazz is pretty much spot on. Players start deteriorating but it's not really a stamina thing, it's an athleticism thing. That's why the best marathon runners can be 40 years old.
These NBA grandpas can still play a load of minutes, just not as effectively or as efficiently because they can't get past defenders, jump as high, or get as much strength/lift under their jumpshot.
Jarrett Jack is AWFUL and him playing more minutes is going to:
-lose them more games
-he get's injured and their D League back up PG loses them even
more games.
