I've heard it reported by multiple sources in the media that Dak was who Kubiak wanted and Lynch was who Elway wanted. Elway seems to have a weak spot for tall QBs.
True Dak did benefit from a good O-line...but step back and just compare the QBs and Dak makes better decisions and seems to know how to go through a progression...Lynch not so much. Lynch was taken way too early...some folks are comparing him to Farve..we can only hope...but I doubt if Lynch will come anywhere near Farve in terms of performance. He just doesn't have "it". Trevor doesn't either but he's a 7th rounder and not expected to. Trevor has over achieved...Lynch has under achieved.
