Stevens praised another local professional sports team, discussing the Patriots' victory in the AFC title game Sunday.
"It was amazing. I think being in this and knowing how hard it is to win a single game, I was telling my son you're living the 60's Celtics, the 60's and 70's UCLA," he said. "That's the kind of thing we're talking about with what the Patriots have accomplished."
Irving addressed the crowd about the late Martin Luther King Jr. just before tipoff.
"Tonight, we celebrate and honor the life and legacy of Dr. Martin Luther King, a man who truly embodies what it means to be a leader, a visionary and a dreamer," he said. "But I think what we most remember him for is for his stance and his action. He fought for justice, equality and, most importantly, peace for all. So, on behalf of the Celtics organization with everybody here, we honor Dr. Martin Luther King today."
