Jake is a rhythm guy that can be really, really good, or really, really mediocre when he's not "feeling it".
The one big positive for him, in my opinion, is that he throws a really nice deep ball on a fairly consistent basis. That was critical last year because you had two guys (Lockett, Thompson) that could really penalize a defense deep. Now that we only have one legitimate deep threat, we're seeing Jake have to rely more and more on an intermediate passing game, and that is not his strong suit, therefore, you're seeing his YPA drop.
Jake can make some throws that the average college QB can't make. He's actually pretty decent throwing when flushed from the pocket, and there's really no throw that I feel he couldn't make. There is a quick strike ability there where we can score within 5-7 plays and within 1-2 minutes that I can't recall with another QB. Those are his strengths, IMO.
However, when he's not feeling it, he lacks touch, throws balls into windows that don't really exist, and worst of all, he tends to sail passes over the middle. I honestly can't remember the last time I saw him throw a red zone fade where I thought, "Wow, that was nice."
My hope is that Jake just takes a while to warm up, like he did last year, when we got to the seventh game against WVU.
