Tired legs, age, pressure, not confident in their jump shot, banged up, or TP guarded by a bigger defender as usual, I really don't know. The Spurs big 3 should not be relying on jump shots IMHO. They are playing against a bunch of midgets so they should rely more on attacking the rim, penetrating, and getting open shots for our role players. This series has demonstrated that the team that dominates the paint usually wins the game, whether it be rebounds, blocks, or points in the paint.
