Butch spoke to that. Said it's all about timing and when the receivers ran slightly wrong routes, it threw off the timing. I interpret that to mean that Worley was adjusting, which explains both him holding onto the ball too long and then throwing behind the receiver.
Again, that's just FWIW because I think it goes without saying that a really good QB can adjust on the fly and make some of those throws that Worley was off on.
Cool. Clearly timing is huge in this offense, so hopefully that will come together with more time and experience. The throws behind the receivers concerned me because faster, smarter DBs could have picked a couple of those.
