Neither is a natural passing QB. And the current offensive scheme calls for a pure passer who can occasionally run it. Not vice versa.
Dobbs is not a natural passer. He is a natural athlete, but not a natural passer. His ball flight trajectory is off unless it is a bullet throw. When it is a bullet throw, his accuracy is very suspect (not timing...accuracy). He can improve as a passer but he is not a natural to throw the ball. If the throwing improves, then he will need to learn to read through progressions. (He often threw to double-covered receivers while not seeing single-covered or uncovered receivers options.)
Likewise, Worley is a great and steady kid, but doesn't seem to have the "it" factor. Unfortunately, I believe he is Crompton 2.0...smarter but about as impactful.
Peterman is in a deep pit. He will have a hard time working back to a starting shot. He is a tough and good kid. He has wheels, but his throwing motion is awkward. In his one opportunity, he made slow decisions. And most importantly, he is not a natural passer.
As I watched all of our QB's during pre-game warmups, the pure passer (tight spiral, trajectory, arm-strength, touch passes) was Riley Ferguson. I have no idea what his decision making is like, but his natural ability to throw the ball is clear. I kept thinking...Man, too bad this kid is hurt because he can THROW THE BALL. Yet, he battled leg injury problems without ever playing a down. He may have the arm but may not have the wheels to play QB. Who knows if he has the mind? I would like to see him healthy and if he has game talent to match his throwing talent.
QB at UT is still up in the air. (pun intended)
