I can't take credit for this, but I thought one of the guys on 1620 had a decent take about a special teams coach. Only the full time assistants can go out and recruit, so you demote Verduzco to an analyst role (which is what he's good at, and he'd still be allowed to coach) and then you hire a full time ST coach who's also a good recruiter.
Assuming Frost is still here next year, another priority has to be o-line coach. I think Austin is gone after this year. That group isn't getting it done and truly hasn't the last four years.
