We had a decent Oline before 2014. I doubt its dominant but good enough to where coach can shuffle effective RBs and wear down the defense. In 2010, I can recall Ronnie Weaver running hard and shredding through the lines, then Tay Murray dispeling him towards the end of the half and wearing the defense down. Same thing in 2012 although not as effective as in 2013. For all i know maybe the OL coached themselves like they did in Miami lol but until someone says that I think Key should get the credit for that.
As for the Broyles nominee, isnt that sent by the teams coaching staff itself? Its not like he finished in the Top 10 or anything, Coach O'Leary wrote up a recommendation to add him to the list. Thats it.
As for Key being moved to OC, I have mentioned in previous comments that GOL should have kept him as Associate Head Coach while adding responsibilities such as overseeing the coordinators - personally i like the title executive coordinator - and GOL having the final say as needed. Its obvious he's not cut out to be offensive coordinator yet - maybe never will be - but doesn't mean he isnt cut out to oversee the big picture. FWIW GOL liked Key because of his attention to detail. I can imagine those details can be as simple as reminding a receiver to catch the ball first, how to block properly, etc. to details on a macro level when it concerns his coordinators. Unfortunately thanks to GOLs poor decision making, Key's career has probably stalled for good.
