I actually thought the play on the Neal shot was classic Tim Duncan. Even with Paul on him, he knows that help is coming as soon as he puts the ball down. Even in 2003, in that situation, Tim Duncan probably would have waited for the help to come as well and would have patiently found a teammate after the help arrived for an uncontested shot.
It's all contextual of course, but anyone who's watched this for very long has to know that with a small guard switched onto him, there's going to be a big coming as a help defender on the first move and that big (with the Neal shot, it was going to be Blake -- and was) will be in a pretty good position to contest a shot without fouling. Understanding that, it was a much, much, much better play for Tim to wait out the pressure and then find the open man than it would have been for him to try to bully Paul with Griffin playing free safety.
