Ketch is right that fans over-estimated Ehlinger. He came into a program without an established QB, and postured well for the role. Desperate for an elite QB, too many of his fans extrapolated Ehlinger's face-of-the-program into assumptions that he was indeed a great player. The reality is that he's probably no more athletically gifted than most other Big 12 QBs, and not as gifted as a few.
Sam's not a great QB, but he can win a lot more games if the staff will find more effective ways to work around his limitations. Pass protection is a huge key. When we have it, our offense seems to click. When we don't, we're toast.
