We all know that Jim Harbaugh likes to get involved in practice. He likes to get involved in player personnel workouts/tryouts, too. Mostly he uses his arm, being that he was a quarterback in the NFL. The players generally say he can still "chuck it".
This seems to fit with the theme of these - the first OTA's under Harbaugh due to the NFL lockout last year - which has featured versatility among the players...now it's extending to the coaches, perhaps, too.
Coming soon: Ian Williams at QB?
