I'm training quite evenly too... which is slow but the effects are showing.
Granted, this is against very poor competition, but 2 trainees in tonight's game:
6k salary 25 pts, 17 reb, 10 stl, 3 blk
5k salary 16 pts, 18 reb, 8 stl, 4 blk, 7 ast
2-3 more years for these guys and they will be trouble, cross-training or no.
