I am very reluctant to pile on a player, usually if I do post criticism I don't even name them specifically.
Alabama's punter isn't only having issues with shanks. As far as I'm aware, only one put has gone over 40 yards, and that one got a really nice roll. So, the shanks are a concern, but he honestly hasn't hit a single punt really well.
To give an example, his long excluding the one that rolled really well is 39. Even if he averaged that, he would be about the 80th ranked punter in college football. He doesn't average that though, instead he's the worst punter in college football and it's not even close. He fell off the list because he doesn't have enough punts, but the 96th ranked guy (who is dead last of the punters who qualified) is averaging 36.9.
Alabama's punter is averaging 34.4. Alabama is basically spotting the other team a first down every time they punt. Honestly this seems to go beyond mere mental problems and seems to extend to some sort of physical problem (like AG). He hasn't really boomed a single punt all year as far as I can recall.
