Daniels would be a fantastic fit for Carroll in specific. One thing no one can take away from Carroll is that his teams have always provided a really robust safety net for the quarterback to lean on. Really helps them grow.
Get him in the organization, get him learning how to operate within structure, get him working on his feet and his mechanics, get him learning how to slide. Beyond that, hell, let the dude shine. He's got the playmaking talent you can't teach.
That said, if Carroll moves on, Jayden's a good fit for a lot of coaches I'd think. Maybe not a Shanny disciple.
