Do good QB's anticipate? I believe that they do. That first read that was covered...do you suppose that a more seasoned QB would have anticipated, based on coverage, that the #1 would pop open? I think that the good ones do. Anticipation is one of the intangibles that we haven't seen on display from a Bills QB.
How many of EJs decisions are made pre-snap? How many of a more seasoned QBs decisions are made pre-snap? Trust (in himself and teammates & bravado (belief in himself to the extreme) seem to be areas where EJ is lacking. Not sure that those are traits that can be enhanced or learned though.
