I'll be interested to see if Belichick uses dual punt returners, one short and one deep, like the Dolphins did in the old days with Scott and Anderson on the Poly Turf.
Fields has been kicking lower this season but often getting away with it, due the to reluctance of the opponent to adjust. They allow the bounces. I wouldn't be surprised if New England is the first one to challenge Fields to keep the ball in the air.
It hasn't been every kick or even a majority of them. One or two punts per game have been atypically low and allowed to bounce favorably downfield.
