When you are a pro and been playing football all your life, there is no such thing, thats just an excuse....like a WR dropping the ball bc he's a rookie..no when you play all your life, you are tooled to not make the same mistakes over and over....can't buy that one, have to put that back on the shelf in aisle 6 next to the trash bags!!!!
This is the first year Bigby has been on the active 53-man roster of an NFL team for an entire season.
This is the first year Bigby has been a starter in the NFL for an extended period of time.
Bigby needs to learn that you can be aggressive without being borderline idiotic by ripping of players' helmets, kicking the ball, etc.
Bigby's has had lapses in focus. You expect those from rookies (which Bigby essentially is).
Rookie WRs have mental lapses all the time, either they don't secure the ball like they should, run the wrong route, of forget to block when a fellow WR is trying to get some yards after catch.
