McHale MUST replace Terry in the starting line-up with Prigioni. This is a key adjustment that has to be made, especially considering having to defend Curry.
Prigioni is light years the better defender, runs the offense so much more efficiently, and is the far better decision maker. He keeps the pace a bit slower as well, which helps the team stay more focused on both ends. Just a much better choice at PG than Terry at this point, it's not even close.
This will allow Terry to stay as fresh as possible coming off the bench. He simply can't defend at all and when he tries, he always fouls. His jumper has also been short throughout the playoffs, so they need to save his legs.
