TE play has been great since Saban arrived - nothing to do with Banks.
Special teams other than the kickers has been great since Saban arrived - nothing to do with Banks.
Banks gets no credit for the above - none.
Yes, he is a great recruiter, but so are the other guys that Saban just fired. He was brought to Alabama to improve the performance of the one area that has lacked consistency since Saban arrived - kickers. He inherited a kicker who performed very well at another school before transferring to Alabama, and one of the highest ranked kicking recruits out of HS. He also inherited the highest ranked punter out of HS. All 3 failed, including the guys who kicked great in college before he met Banks.
Maybe he will improve in 2019. I hope so. But he had one job to do in 2018 and he failed.
