Holding? Pass interference? What the **** is wrong with you? Those plays are penalized in game because they gave an unfair advantage, that's it. It isn't deemed malicious to hold a guy, or to interfere with him catching the ball. You don't risk injury with a hold. Clipping and illegal blocks are 100% fineable. Ask Flozell Adams.
