There will be the predictable difficulties with transitioning to a complex offensive scheme with which he is has no experience, one which places additional responsibilities on the QB; but we heard as he was being vetted prior to being drafted that he is an intelligent and studious player, so the adjustment should be reasonably brief. We know too that he will be be adapting to any number of new players, which also will take time, though on the other side of the scale, at least these new players are pretty certainly better players than the dismal and poorly-coached group he had to work with last year. His coaches this year are far better than what he had last year, Lord knows.
So I expect there to be a reasonably brief period of adjustment to all that is new, but that by the end of preseason he will be in a position to develop steadily over the rest of the season. I suspect he'll tone down the "Aw shucks" stuff over the course of the year, I expect the turnovers to drop off as he continues to adapt to the greater speed and complexity of the NFL game, and to the superior speed and skills of NFL athletes, and I expect that as he masters the basics of Josh's offense, he and Josh together will work to adapt the offense to take advantage both of his innate athletic assets and of the skills he learned playing under a different system in college.
The takeaway, I guess, is that I expect him to develop just as we have hoped he might, after a perfectly acceptable period of adjustment over the course of the preseason. I suppose that's a pretty luke-warm, generic take, but I just don't see any rational basis for anything more entertainingly dramatic, and I think it's way too early to be attaching numbers to our projections for Drake or any other player.
If Drake doesn't develop as most of us have expected he will, that'll be a huge disappointment, but I don't see that happening
