It just seems like the obvious thing to do. Players having a problem with his defense...and he is in the booth. There is something wrong with that...right? If he wants to implement his new system regardless of the results so far, fine but he can't teach in the box. He coached the secondary before and his secondary has two young corners, he needs to give them the ease of open conversation on the sidelines. If they ever click to it, then he can gladly go back to the press box.
"If you want something done right, do it yourself", stated Fitzgerald when asked about the current QB situation. He will now be throwing to himself.
