What penalties would you change and how?
One penalty I feel is too strong is the offensive holding penalty. 10 yards is appropriate on occasion when the play would have resulted in around a 10 yard loss if not for the hold. But most of the time the defensive play would have resulted in something much smaller.
On a running play, what if the running back was at the line of scrimmage when the hold occurred? Is it fair to march the ball back 10 yards from there? I think not.
I would suggest reducing the penalty to 5 yards or spot of the ball when the foul occurred, whichever is longer. Or make it a pure spot of the ball foul but add a loss of down.
But a straight 10 yard loss is fairly often just too harsh and kills too many drives.
What do you think? And what other penalties do you have issues with?
