Well we could pull a Billicheat " It's not against the rules..... yet" type of thing and start a genetic baby factory and withing 20 years or so we'll be a on going dynasty!
I don't get how the guy who has the best deep throwing arm statistically in college football last years arm reminds you of AD? If I'm not mistaken AD has always been compared to Petty as his Pro comparison.
Deep passes and a strong arm, don't necessarily correlate, especially when you are talking about the context of what they did in college. If anything, having pocket protection, and a WR with long speed, or a certain system correlate better with that stat.
As far as arm strength:
@jrry32 proves that it doesn't mean everything, by that list.
It's nice to have both though, see Aaron Rodgers, and that is one of the differences between him, and Andrew Luck. Rodgers still has the arm strength to squeeze deep balls in late, over the middle, because of his big arm, and accuracy. Luck, gets those passes picked off. Having a quick clean release is a big deal too, when we are dealing with fractions of seconds that can make the difference in getting stripped, or getting rid of the ball.
There are tons of other attributes that make a quality QB, too many to list, and even if I listed them all, no QB has them all. It's an imperfect science-- finding a QB, but if you are building one, which is what we have to do, why not start with a guy that has the most weapons in his arsenal. There are probably only a handful of guys that could be successful in every different type of system in the NFL. Being the right fit, means more.
Looks to me like we are building a system like our division rivals, good defense, special teams, ball control, and trying to limit mistakes. We don't need Aaron Rodgers, but I'd sure like to have him.
