Havn't noticed anything about kickers but what I have noticed is punters averages going backwards from fresh to senior years. My punter was a freshman at the start of 3.0 and his average has gone slightly down every year. He is a senior this year so i will have my data complete soon.
What I find interesting about this is that this was a problem of 2.0 that (yeah thats right) never fixed. Hmmm. what are the odds of this happening in 2 different versions of the game. Or perhaps punting NEVER CHANGED!!!
