I've seen some pretty interesting stats on ESPN, NFL and maybe somewhere else showing how his numbers on deep passes (15+ yds downfield) took quite a drop his last season here. And I've read/heard in various places also that the arm just isn't there to throw those passes right now. Will the strength return with more rehab and playing ?? I'm sure Peyton would like to know too.
If he needs to rely on pretty much the short game, it's not going to take long for defenses to start giving him the deep stuff and dare him to throw it. Then we'll see what he's got.
