I'm with Bbills on this. Football is a game of yardage and movement with scores only happening sporadically compared to the nba game where movement is a given and scores come regularly. of the 4 examples i think all are lame. what i would instant replay is shooting fouls and even then its way too subjective to call. is instant replay going to stop all the tickey tack fouls on wade? No way. Its subjective as to HOW MUCH contact is allowed and where contact is allowed.
