The Pro Day slate begins this week, a stretch that’s undoubtedly one of Bill Belichick’s favorite team-building exercises. (To get a reminder, check out this piece from Jim McBride on Belichick on the road last March .) Belichick has a few other team-building questions to tackle over the next few weeks, but the chance to get out on the road, get a look at some prospects and size them up as potential Patriots is an annual Belichick tradition this time of year. So pack up your Johns Hopkins lacrosse pullovers and Vineyard Vines gear — here’s our guess as to where Belichick’s itinerary will take him over next three weeks, as well as some of the more notable Pro Days on the schedule.
