Do you want Brady to have a cup of coffee back there in the pocket? Since 2016 there have only been 10 instances where a QB has taken over 3 seconds on average to throw a pass through the course of a season (128 pass attempts minimum). Yes I'm sure there are instances where the line provides good protection and the QB might have 4 seconds. However, it looks like 2.5-3.0 seconds is the normal amount of time it takes a QB to release their passes.
I'll agree the line needs to give Brady time, and if they do he will carve up just about any defense with the weapons he has. If he has 4 seconds to throw his passes, every lineman on the Bucs better be in the Pro Bowl and eventually be Hall of Fame candidates.
