Here's another way to look at the play.
If West wasn't already hurt, would we be having this discussion? Would anyone have even noticed this play? Would this play alone have injured West, if he wasn't already hurting?
If the answer's "no," the next question is...
Should Robert Horry be obligated to change how HE plays basketball because the other guy is trying to play through an injury?
This pick was a very common play - basketball's an inherently physical game. They give you six fouls for a reason! If West's body can't handle the physical demands of playing (especially at the 4 spot), he shouldn't be playing, you can't expect the other guys to coddle you.
