This is why I am adamant about them changing pass int. to a 15yd penalty like in college.The calls are to inconsistent and can and do have a major impact in game results,which is not fair.How come offensive pass int. is only 10 yds but defense is spot foul.Most times the offensive player is just as guilty or even causes the interference with all the hand-checking they do. You can practically maim or injure someone and only get a 15yd personal foul penalty but if you interfere with a pass it can be 50yds or more sometimes .It doesn't make sense. I know some of you are going to say that all the defender will do is tackle his guy if he gets beat ,well so be it, it would just be part of the strategy of the game.The offense is at enough of an advantage.Either that or they need to make certain penalties or in this case non-penalties reviewable.
