I wonder, though, if the injury is bad enough that he's affecting the team negatively because of it. If that's the case, shouldn't his minutes get trimmed? Obviously, Miles has noticed the same significant difference in his play the rest of us have (as he mentioned in his radio show). Is his considerably limited offensive abilities (due to injury) right now hurting the team more than his defense and rebounding are helping?
Miles thinks Biggs' defensive lapses are hurting the team more than his offense is helping, so he pulls the kid.
Give that, I guess Miles believes Shields is still helping more than he's hurting.
