Bill Belichick grew up around college football. As a child, he tagged along as his father, Steve, went about his duties as an assistant coach at the United States Naval Academy.
But his own five-decade coaching career never took him back to the college game until recently. And in that time, and especially in the past few years, the sport has changed tremendously.
There are now name, image and likeness rules, or N.I.L., that allow players to be paid directly, sometimes to the tune of millions of dollars. Players can use the transfer portal an unlimited number of times, which has led some to school-hop each season.
