Well, if you need any advice, BBmail me. I train PF/C, and occasionally SF, too. I only train the whole team in Stamina or FT every 8 weeks.
Enthusiasm is very important. Last season, after I was locked in the playoffs, I TIEd the remaining games leading up to the playoffs to maximize my enthusiasm for the postseason. I think its the main reason I made it to the finals. It's a bit unrealistic, but it's part of the game, I guess.
