I'll make this short and simple.
IMO, regardless of what has been reported and how he has actually looked, Drew Henson has improved.
I've been believing this for quite some time, but couldn't think of a way to explain it.
But here's the best I could come up with...
Drew Henson last year was at a stage comparable to taking basic math. He had a decent understanding of what he was being asked to do.
This year he's moved up to College Algebra. A lot of people struggle when they first start taking College ALgebra, but after doing a few hundred equations, they start to get it, and it gets much easier.
For another words, Drew is struggling cuz he's moved up a lvl in his development. He's actually TRYING to do the more difficult things now (such as fine tuning his throwing motion and reading defenses). Once he gets a good grip on "College Algebra" he'll move up to calculus (or whatever, you get the point) and he'll struggle again, and so on and so forth.
It's kind of like being a QB and going from highschool to college. The playbook is bigger and the defense more complicated. But with Henson it's more advanced cuz he sat out 3+ years. He's getting it, it's just taking a bit longer due to the layoff. But we signed him long term for a reason.
Hope that made sense.
