Who was the young WR's coach who Devaney let call plays in the early 70s?
I'm not saying that Frost=TO, but to catch young coaches on the rise, don't you sometimes have to "take the risk" of promoting them to the next level of responsibility? Of all people, TO and Bo (circa 2003) should know this right?
I'm not sure if it's the "calling plays" part of the OC job that would concern me, it's everything else. Politically, giving him the OC post wouldn't be the best move for the rest of the staff. This is different than 03' IMO. Beck would pissed no doubt. Who knows how some of the other guys w/ more experience would feel. Barney might be slightly ticked.
Also, there's a lot more that goes into being an OC than just calling plays. There's a ton of logistics work - coordinating staff, players, meetings, etc. The management aspect of it is something he has no experience doing.
For Frost's sake - bringing him in as an OC might not be in his best interest. There'd be a lot of pressure to perform, and a political firestorm to extinguish. He could be successful no doubt - I'm just not sure he would be as an OC for NU in 2011.
