I written several times on this site, including at the beginning of last season, that I thought TT needed to step up into the pocket. I have also posited that his ability to do so would take pressure off the O-line, and RT in particular.
I don't necessarily agree that this is an "either you have it, or don't" attribute. Accuracy, mental aptitude, certain mechanics, perhaps-- these are the things that can't be taught. I think that many such attributes are things that Tyrod already possesses. That's the good news.
You can't teach his athleticism.
But, stepping up into the pocket? That, I believe is something that is easily understandable. I think it just takes awareness, proprioception (which TT has miles of), discipline, and self-confidence. I think it also takes some real chemistry with the O-line.
I think Tyrod can get there, and I think his game takes a significant step forward if/when it does.
