Doug Williams tells TMZ Sports he teared up after Patrick Mahomes and Jalen Hurtsofficially made the Super Bowl ... comparing the moment to when Barack Obama first got elected.
Williams, the first-ever Black starting quarterback to win the Lombardi Trophy, said the tears never quite spilled over onto his cheeks -- but he said they were there, and they were filled with happiness nonetheless.
"I had tears of joy in my eye because I had an opportunity to witness this," the former Washington signal-caller said.
