It kind of confounds me that kickers can be great in college and then really struggle in the NFL. Outside of winds, isn't it something that should directly translate from college to the pros?
College goal posts are 5 foot wider, so the margin for error is smaller. Might need to scout distance from midline/check how many FGs were "barely made" in college more than simple make/miss. I also think people underestimate the importance of the other people that are involved, and developing familiarity with those people. I'm not sure if alignment changes or not (holder same distance from snapper, that sort of thing.) I do wonder how often ST coaches try to get kickers to do things the coach's way and it messes with the kicker's confidence. Or even something like snap speed, a different timing can throw off rhythm.
It seems a lot of the time Kickers practice off tees. (I could be wrong.) It never really made sense to me. Kicking FGs like you will in the games as much as possible would seem to make more sense. How well does a tee really simulate the holder? One also doesn't get practice for when things are (inevitably?) out of synch.
