Fans are too accustomed to it.
I'm not fond of it in regard to penalties... I actually like it as far as two feet in and 'was it a catch/fumble'. But I could live without at.... and speaking of 'two feet in' I would love to see the NFL go Collegiate and make it 1 foot in. Couple of reasons... risk of injury lessens and it's the one thing, (Being a defensive guy), I think would greatly create more O and be worth it. Being able to get two feet down I will admit is an amazing feat.... but one I could do without.
Pass Interference is a lost cause, there is no perfect solution and never can be, instant replay or not. The ONLY thing about PI that I wish they would begin doing is following the rule book and actually calling it as it should be - that is: The D has has much a right to the ball as the O. - JamesJM
