Actually, there's another factor in one-on-one play that Iverson overlooked: when Zhang Yang drives into the 76ers' paint, there's no one to stop him, so Iguodala must be on guard against being beaten, while Zhang Yang doesn't have to worry about that.
Iverson may not have neglected it, just considered it part of one-on-one play; after all, this kind of thing can never be fair.
Iverson took over the offense and now it was Felton's turn to worry.
With Iverson's change of direction and breakthrough, Felton managed to provide the first bit of contact, but couldn't keep up after that.
Iverson closed in, came to a sudden stop and sprang up, his legs acting like they had springs installed. Okafor stepped up to block, but Iverson got the shot off before Okafor's block could land... and it hit!
When it was the Bobcats' turn to attack, Iverson actively went up against Zhang Yang; reluctantly, Iguodala had to switch to guard Felton.
