The holding the ball rule needs to be clarified over the off-season.
I watched 7 games over the weekend, and there was absolutely no consistency with the holding the ball interpretation across those games.
The biggest issue is with dropping the ball I reckon. If there is no prior opportunity, the player is given leeway to just drop the ball or dispose of it by any means (legal or not). I understand if the ball is knocked out in a tackle, but a player should still have an onus of disposing the ball legally, whether he had prior opportunity or not.
Yeah, and I've noticed if you've got the arm pinned, it's like catnip to the umpires. If the arm is pinned you don't get prior opportunity, while if the arm isn't pinned you can either get a ball up, or shovel the ball out however way you like. It's always struck me a little unfair. If you arm is pinned it's pretty hard to get rid of the ball properly so you should get some leeway, while if you have two hands free you really should get rid of it properly and there's no excuse.
