"We've had a lot of big wins here in Pittsburgh," Belichick told his team ... "We've had a lot of big wins here. I think it's fitting that this one comes on Mr. Kraft's 500th game."
Kraft -- who's owned the Patriots since 1994 -- was choked up ... but managed to speak a few words after his players implored him to deliver a speech.

RK said he and his son, Jonathan, have the opportunity to work in different business industries, but none of them compare to the NFL -- mainly because of the players' impact.
Kraft has enjoyed a lot of success during his tenure as the Pats owner -- the team has won 6 Super Bowl championships and was a perennial powerhouse during the Brady/Belichick era.
