I would take a balanced player like the 13/13/13/7 guy with good guard skills mentioned over an unbalanced player with high ID every time.
I think far too many BB managers are far to quick to sacrifice balance for high defense and they end up with great defensive teams that can't score efficeintly.
That's not to say that defense isn't important, but I would argue it's all important and you shouldn't put too much focus on one aspect.
