Do we know exactly how Shot Blocking works? For instance, on the 0-2 Jump Shots, perhaps his better shot blocking allowed him to 'Contest the Shot' forcing the misses. And perhaps Shot Blocking is why it went from 'Unguarded Post Points' to at least having a Defender on him to increase the chances of a miss.
Again, I have no idea how SB works or if it affects shots (other than by blocking them).
(I see now that moutlinho says SB does 'alter the shot', still I don't know how often or to what degree.)
