People here have such short memory spans.
In 2013, brady had possibly his worst receiver corp in years. Thompson,Dobson, an injured amendola and Edelman. that was IT. Gronkowski was injured that whole year.
and guess what? Brady's stats suffered. he looked poor most of the year only threw 25 TD's and most of the mediots/fans declared the decline is here!
Then guess what? Offense was healthy the following year brady looks good and they win a superbowl!
Then 2015, brady is on fire. then we get injuries to Edelman and hes throwing to guys who arent in the league anymore and his stats suffer.
2016 - team is relatively healthy, brady is on fire and they win a superbowl
2017 - brady starts year off on fire despite injuries to edelman. Then injuries hit his #2 receiver Hogan, gronk misses a game(2 technically) he misses burkhead, white(superbowl MVP) he is throwing to Kenney britt brought off the street. and his stats take a dip.
It isnt hard to see that the effect of players out there with brady affects the offense and his stats. THe pats offense is based Totally on pre-snap reads and knowing where to be. If the receivers are guys off the street and dont see things the same way brady does then the offense isnt going to look sharp.
So YES, the players around brady do affect him/the offense. and there is a much larger sample size than 5 games.
