Army wildcat QB Bryson Daily

Did anybody know Taysom Hill could do those things before he did them?

No. He was a guy who did a little, then showed a willingness to do a little more, then kept adding to his skills over time. This expectation that guys come pre-fabricated and fully formed with demonstrated evidence is half-baked. After measurements and intangibles, the only thing left is to imagine possibilities. Daily wouldn’t make it at the next level expecting to solely play QB, the way Taysom thought he might all the way up to the point when the team changed his position to drive the point home: “throwing is one of many things you’ll do on this team.”
You’re right, but in order for someone to fill his role or even a portion of his role, they need to be able (and WILLING) to do those things.

There have only been a handful of ex QB’s who’ve transitioned to other positions in the NFL and actually been successful, and none have succeeded at multiple positions/roles like Taysom has as a QB, runner, blocker, receiver, and special teams player.

Finding a running QB that can come in on some downs and get some yards is easy to find, the NCAA is full of them. Finding someone that can actually do all the things he does consistently is not so easy.
