No Jaj, a mock draft is supposed to represent who a team will draft and where. These have nothing to do with now and will change then. That's why they always say it's early and these predictions will change. How are these teams supposed to know what these kids can do against other kids who are NFL talented?
The interviews, combines, invitation games and other things have not even taken place. Ben Roethlesberger could go to the Senior Bowl and struggle with the speed and athleticism of kids who are actually good and those two seconds he has to make a play become one and a half. The window that is open closes and he has trouble making the throws.
What if he does poorly in his interview? This could cause him to fall. They seem to think so. It's no more ridiculous then thinking any other player could fall.
