I know it's overplayed, but Tom Brady was a 6th round pick. The idea is to find someone that might not have had great coaching, was behind a guy that fit the team's offense better, has all the tools, or has no tools but still wins, a late bloomer, etc, etc.
I expect EJM to be the starter, and play a couple notches better than Orton, which is probably enough to make the playoffs.
