Well I got some shorter players through draft, and just sticked with them. But if I was training centers/PFs I would definitely train SB, for the fact that SB is cheap. Even without those changes few seasons ago.
Some more experienced managers were telling me that I need high ID, but I didn't really care, I mean, 17 ID 8 SB can't stop LI anyway. So who's to say 15 ID 14 SB is going to be worse? It's still more skills total, so I would certainly try to build high SB players, even under old GE and salary formula.
