My initial thoughts:
They trusted him enough to get the start while protecting our biggest asset. He clearly understands the playbook enough to get the nod.
What he lacks in physicality, he makes up for in effort and physical traits. Not a great punch in pass pro and locks out arms, holds on for the ride so to speak. I would say, I'd be pretty nervous going into a USF/VT with him at LT. My question is how long is the learning curve for him to get a real feel for the position. Gotta get comfortable enough to win the pass pro fights with single punches rather than throwing both. Better players will have counters.
I do think he moves well enough to play here though.
