My condolences, Coach. Thinking of you and your family.
I'm going out on a limb : arrangements will be made to coincide with what works best for BB's football.
Belichick's dad died the night before a game in 2005, he coached that game and the game after.
With all respect and kindness intended, a 98 year old with an only child doesn't usually have too many people to accommodate for arrangements. Plus Covid.
My condolences to the Belichick family. The grand kids are on the coaching staff too.
