Not attempting to assign specific blame here to Mayo or AVP or Maye, and apologies if this was mentioned upthread, but one sign of a poorly coached team to me wss after the successful fake punt (and due credit to the staff on that), the offense was not prepared for the next play and had to take a timeout, which could have proven valuable at the end of the half. The offense should have been ready immediately and even should have had a play called while running the 4th down play. Inexcusable IMO.
A couple of years ago I was listening to WEEI's morning show (I know, I know, but I had a long drive...), and they had Charlie Weis on for a segment. And Weis mentioned how one of the jobs as offensive coordinator is to have a couple of plays ready to go based on the play call you just sent in. And those pending plays were to be based on a couple of likely outcomes from the play call you just made. For example, as OC, if you call a deep throw on 1st-and-10, you should have a play to call in case the pass is made (presumably in much better field position), as well as a play ready in case of an incomplete pass and another one in case of a check down play that nets 3-4 yards.
A fake punt is about as binary of an outcome as it gets - they would be facing first-and-10 on their own 25 (which was the case), or sending in the defense. So no excuse to not have a play ready, if that was the reason for the timeout.
The only good reason for a timeout there would be if the defensive formation or personnel was something totally unexpected, and given it was late in the first half taking the timeout would be the right call in such a situation.
