Pro days don't mean squat. He showed what he can do during games, he's definitely the best QB prospect.
Some team is going to talk themselves into Bortles ahead of Bridgewater based entirely on stuff that happened after the college football season ENDED, and they're going to regret it in a few years. GMs regularly get fired in this league and most are horrible talent evaluators, don't assume because one guy gets drafted in front of another that it was a wise or even prudent decision. Remember, the Bills were dumb enough to take an athlete playing QB at #15 last season instead of taking the natural passer that fell to us. Bad franchises do stupid things, expect more of that in this draft
