To put into context with playing styles and our offensive coordinator:
I'd be willing to bet that Haener can be almost as good as Brock Purdy and can win within a system before I'd bet that Rattler is Jayden Daniels as a rookie and can win games on his own with subpar surrounding talent
Regardless, give Haener first shot at it. If he ain't it, fine. Put Rattler in.
I don’t think Haener has a prayer of being the answer, but this would probably be the best move. If he does well, great. If not, Rattler comes in without the pressure of by passing the QB who was above him on the depth chart first go around.
