Mahommes will be long gone by the late second. The thing with the system argument is that almost all of these guys are coming from spread offenses. You're really limiting yourself to schools like Stanford, Michigan State, and NDSU if you aren't going to take a chance on these guys.
I have no problem with Goff going as high as he did. I think Wentz was better, but I can see why people really liked him as a prospect. I still think he'll be a decent QB in the league. My sleeper pick (kinda) would be his replacement Davis Webb.
