This goes to show that bb loves the kid.
Any thought of upgrading Andrews is effectively over.
However we can still hope that mason improves as a pass blocker or karras/Garcia can slide into that spot,
I think he really likes Andrews but if Belichick sees an opportunity for competition or an upgrade he will still do it. Just look at WR, they just won a Super Bowl with their current unit but Belichick still spent a 1st on Cooks. If he sees a great Center prospect sitting there when he's picking next draft I wouldn't be at all surprised to see him take them, after all, he called Stork a " once in decade" center but still went hard after Andrews.
