2. The Heat's pick-and-roll defense will slow the Spurs' offense
The way Miami defends the pick-and-roll night in and night out is how the Thunder defended the pick-and-roll after the start of Game 3 in last season's WCF. They are going to blitz Tony Parker and force him to either play in a crowd or give the ball up. Most teams can't get away with this strategy but it works for the Heat (and worked for the Thunder) due to elite athleticism on the weakside when recovering to shooters.
Plus, Miami is even better at this style of defense than OKC because they do it so often. I expect them to blitz Parker relentlessly in an effort to make someone else beat them.
In the starting unit, there really isn't a pressure valve for TP. Can Danny Green or Tiago Splitter pop open and create plays after Parker gets trapped? Hopefully … but obviously far from certain.
The obvious solution for the Spurs would be to pair Parker and Ginobili as often as possible. Thus, when Parker gets trapped, he gives it to Ginobili so he can create with a 4-on-3 advantage. Again, hopefully that works, but at this stage of his career does the Argentine have the wherewithal and stamina to create consistently in a seven games series against an athletic and aggressive rotating defense?
Boris Diaw is another possible remedy … but will he be enough of a scoring threat for the Heat to respect his shot? If not, could Bonner come in and knock down the biggest shots of his life?
I just don't have confidence in any of these scenarios.
