There are keys to the series then there are the guys who, should they perform, make it hard for teams to overcome. Obviously, in the case of a Mario Chalmers or James Jones, should both of them pull their best Vashon Leonard or Anthony "off the top of the backboard" Carter, then the heat will have a distinct advantage. Jones has had an off season, while Chalmers has been outstanding from deep making 101 triples this season. Between Jones, Shane Battier, Chalmers and Mike Miller the heat have made 262 threes this season spreading the floor for the Big 3. ?Their .359% is 9th in the league mainly because Wade and James aren't great from deep.
I can also see Battier making one or a few killer corner 3s during the series that will make me want to throw my TV out the window.
