Belichick will be 63 this April 16th (which also happens to be my birthday btw). I’ve always felt like he’ll stay on a few years after Brady is done. He’s spoken in the past about the admiration he has for San Francisco keeping their dynasty going through a second quarterback and something tells me he’ll try to do the same. He’s shown no signs of slowing down or taking any less enjoyment out of the grind, so I’d bet we have at least five more years of BB, maybe as many as seven or eight. But he has said he doesn’t want to be like Marv Levy coaching into his 70s, we’ll see if that holds true.
