I disagree. That's not Brady and BB.
I guarantee you Brady was obsessed with beating Miami on the road and getting the divisional step-up 500 times more than the 100 game milestone.
IMO, that was emotion over winning a big game when much of the world was dissing the team during the week.
Look historically back at those two. The personal accomplishments, they never really made any big demonstrations about - - the 50th TD pass, the 100th win as a NE coach, the win the day after BB's dad died etc. These two never make it about themselves.
Anyone who has followed these two over the years knows that when you see them celebrating on a field it is always from a team win - - watch the DVDs of BB in 2001, 2003, 2004 - - BB celebrates on the sidelines when there is a TEAM performance, same with Brady - - his biggest demonstrations are always for the win. Honestly, have never seen him demonstrate after a personal milestone.
