Per Mortensen, Brady is “uncomfortable” with some of the changes to personnel and the coaching staff and that he has seen his level of input into the offense — things like game planning, pre-snap adjustments and personnel packages — drop of late. There’s no question that the Patriots have failed to find receivers talented enough to help Brady over the last couple of years and their offensive line, which saw guard Logan Mankins depart in a trade just before the start of the season, has been a mess this year, the first without the now-retired Dante Scarnecchia coaching the group. The shortcomings in those two groups come after the Pats used a second-round pick to take a backup quarterback a few years after doing the same with a third-round selection.
