You're right.  Anyone can be a coach, particularly at the pro level.
In fact, here's my game strategy for this weekend's game for the Tampa Bay Buccaneers: Pass, Run, Run, Run if we need less than 2 yards/Punt if we need 2 yards or more.
Think that's good enough for the Glazers?
Oh, and there aren't enough Scottish coaches in the American pro leagues, either.  Hoot, man!
