There are actually 3. Pro, DT and overall.
To use a Video game term. The meta in scouting and in the game itself is changing. In the past mobility was more an afterthought. DT QB's are undervalued it was always he can run but can he throw. Now its he has a great arm but is he mobile? We might be looking at the last of a dying breed when pure pocket passers were what everyone wanted. I think both extremes are wrong but kinda necessary now. It used to be each was separate and went into totally different systems but now with things like the spread/air raid which can work with both types it comes down to what guy has the best total package. Look at the past few drafts. Most of the pro types that were drafted would have been called DT's 10 years ago. Seriously think about it.. Before Vick, Steve Young, Steve Mcnair and John Elway were what passed for a dual threat QB. Pretty much every QB taken in the first 2 rounds this past year would have been a mobile freak in the early 90's and people would be questioning their arms. Like they did Warren Moon and Randall Cunninham.
Guys like the Mannings and Favre represent the last of a breed of Pure pocket passers. Not because those guys don't exist anymore but because with todays level of athlete you cant survive in the pocket. Look at todays top QB"s in the NFL. Check their rushing stats and they will surprise you. Compare that to even 10 years ago. Most of the guys we consider Pocket passers would have been DT's 20 years ago. Bailey is trapped in an era where lack of mobility whether real or perceived is seen as negative. It sucks. That being said I am glad we have him and I hope he p[roves those who doubt him wrong.
When I look at his tape I definitely don't see a statue. I honestly think if the guy decided to take off he'd surprise some folks. I also see a guy that needs some meat on his bones before he decides to try it. Better said he is just not dumb enough to put his frame out there like that. Look at him move in the pocket. He has great lateral movement avoiding pass rush. Let him put on 20 or so pounds in college S&C and fill out that lanky frame.
End of day we got our QB he is what he is and at this point I dont care what hes rated. I like him.
