yea maine, thats my number one concern with doc so far, why is it that at both the bbd/powe matchup and the house/sam matchup, the PT is decided in advance and no amount of struggling will force a chance for the other?
as you said, send the guy out thier for his first shift, evaluate what you see, and if you have to, make the change.
sam was a perfect example of this in game 4. he clearly didn't have his shot, and when he doesn't hes a huge liablity. why not toss house even a 4 minute shift and see how he looks?
but no, doc stuck with sam come hell or high water...i just don't get that mindset.
