Besides the absurdity of needing an additional week to sort the AD position, this last sentence is a little concerning, but I'll still take it if it means we're finally a perennial top 5 team in a few years.
The AD needs to have some control over football.
For instance, if Mario can't break through 10 wins and get into the playoffs because he doesn't pass the ball enough, or becomes too loyal to an assistant and that part of the team is the last thing needed to break from strong team to elite, then Mario needs to have someone talk straight to him with the slight threat that he needs to make changes, however, he will be looked to for those changes and not the AD or BOT's.
That last part is the only thing that makes my stomach a little funny. Accountability is needed at every level. That stated, I definitely believe that Mario needs, and will require, a lot of rope and latitude to build the program, which will include some pops of failure along the way.
