The calls where a qb's helmet is grazed is ridiculous. its impossible to rush the passer these days in fear of the momentum of one's arms making contact with QBs head. Also these tacky tack pass interference calls are silly. its totally random when some of these contact after 5 yards penalties are called. pass interference should only be called for most egregious offenses. Lastly, holding calls are so random, everyone holds, some are called and some are missed, and on top of that, some imaginary holds are called. I don't know what the solution is, but these games being decided by bad calls is bad for the game.
