Pardon my Engrish
Wilt averaged only 51.1% from the line.
Shaq had a childhood injury that makes it hard to flex his wrst (or so I've read). I doubt he's ever going to be more than a 60% guy even if he focuses on it.
The harder issue is with Skinner. Here is a guy who can hit jump shots but was very bad at the line. A rule change would be huge for his career.
The difference is Shaq and the only reason this is even talked about is because Shaq is a game changer, it's not an issue with Skinner, he is a dime a dozen player, you can take him out of the game and you lose almost nothing (maybe his fouls). So no one is going to change rules because hack a Skinner doesn't completely change the game. I guess at somepoint another super star will go through the same issue, so it makes sense to fix the rule now.
