I like how people think that if we would have drafted Dak, he'd be playing for us like he is in Dallas. They are one of the most talented, if not most talented, offenses in the league. If we drafted Dak, he'd be third string, and would probably be bad to mediocre....especially with David Lee coaching him up.
But he has been solid in Dallas. Throws bad passes, but finds ways to win games. He kinda looks like Rothlisberger (more athletic obviously) from his rookie year.
Ultimately, I think it comes down to a good coaching scheme and bringing all talent on offense first, then drafting a QB and plugging him in
