the thing is and this is just me off the cuff, but I hate them for various reasons. We tend to think of 100 yards rushing, 100 receiving and 300 passing as the "big day" kind of numbers, but to me it seems the latter two are in general harder to get. I think the bonuses can be harder to synch up fairly. Plus, as others have said, you are already being rewarded. The cutoff is too arbitrary. 99 yards and 100 yards is a bigger difference than 98 and 99 yards, which seems wrong to me.
The opening scene of the movie "Saving Private Ryan" is loosely based on games of dodgeball Brian Dawkins played in second grade.
