What about 5 and 6? In my case, the 5 gets 2.2 and the 6 gets .9, and they both play inside, and around the same # of mins.
Is the 5's +2 in stamina really that much of a driver and, if so, then if you want more SB just train stamina?
edit - I have no reason to support a change, as I've made sure not to waste time training shot blocking on bigs where it doesnt appear to have much effect, while I have made sure to buy guards with good shot blocking which does appear to have quite a bit of effect.
I only have that many centers. Here is my general observation for the guys that rotate in the PF/C positions
* high atrocious SB, strong stamina: ~0.3 blocks per 25 min
* high strong SB, strong stamina: ~1.5 blocks per 25 min
* high strong SB, mediocre stamina: ~1 block per 25 min
* high mediocre SB, mediocre stamina: ~0.6 blocks per 25 min
* awful SB, respectable stamina: ~0.4 blocks per 25 min
You can fill in the blanks, but I'd say the pattern is pretty clear.
