New England Patriots fullback Jack Westover claimed that he switched from the No. 87 jersey to the No. 37 for two reasons.
One of the reasons is that he wore the No. 37 as a walk-on at the University of Washington. So there's some history with that number.
The other reason is the fact that the No. 87 jersey belonged to Patriots legend Rob Gronkowski, who is viewed by many as the greatest tight end in NFL history. There is a great deal of history that comes with the No. 87 jersey in New England.
