That's why I was careful to only talk about his mobility which I think is fair to judge from that game since he was running for his life. I looked like a guy who could get out of the pocket and run in college, but it's clear that he doesn't have the athletic talent necessary to do that in the NFL. I do think he left a lot of yards on the field in that game and didn't do a good job reading the blitz and hitting the hot route, but I won't judge if he can do that on that game.
As far as the rest, I just don't think Book was a particularly impressive pocket QB in college and he has a decent arm, but not an amazing arm. Anyway, I'm just saying that he is not a clear cut future starter and he's not some amazing natural arm talent guy that just needs to learn to play within himself. He could develop, but it's not sure enough to pass on a QB that has elite arm/leg talent and that you think you can develop into a franchise guy. I don't know if Willis is that guy, but given his natural ability, he is probably worth a shot if he falls to the 2nd or 3rd. And, for all I know, the Saints see something in him and think he's a 1st round talent. The truth is that #18 isn't that high of a pick to spend on any QB and they would still have a lot of picks left to address WR, TE, FS, OL depth, and DT depth.
