My problem with SB in real basketball is that I use to see them as bad defence, because a lot of players go for the block instead of defending properly. Duncan, Marc Gasol, Spliter, they dont jump or block but are very good defenders. Maybe is also that I can't jump...
Anyway, going back to the BB world, I am glad that you explain the GE so clearly to us. I think I am going to try to build inside players with SB in my Utopia team and check for myself.
