Oh no doubt. You wouldn't even get invited to the combine for the league T Rex is playing in. If they ever open the Frustration Hall of Fame, his bust is going sit atop the rotunda.
Assistants are overrated, I'd take players any day. It's not even PC to ask them to get you coffee anymore and if he messes something up HR doesn't even allow you to make him run suicides.
Back to Knox - if he's on-field I'm assuming it has to be special teams. Other than loyalty maybe I'm not sure why you take him. Gonzales has been with him everywhere, and that was a given. Seider seems to be both a good recruiter and position coach, so I can't see the logic in bumping him. I'd rather have someone else in the ST spot.
