Fitzgerald is the first African-American amateur to win the team title portion of the tournament and, according to Cardinals media relations, just the seventh professional athlete to win and first since Dan Marino in 1988.
"It's great, but I'm just hoping moving forward we don't have to talk about color anymore," he told reporters. "It's just us as one as a people. Just to be here is an accomplishment. But that's quite an accomplishment."
Fitzgerald and his friend Streelman won wire-to-wire.
"Just being completely out of my comfort zone, not being a professional, just kind of dealing with what comes," Fitzgerald said. "That's what I think made it special for me, is that this game is so difficult.
"I just think you even have more respect for the guys who win and play consistently at a high level because it's the hardest game out there."
Streelman told ESPN that the victory is "something that I will never forget. To win this with my buddy."
Fitzgerald is still contemplating his future in the NFL and said at the Super Bowl that he would make a decision on his playing future in the next "week or two."
Fitzgerald, 34, tied a career best last season with 109 catches. He also had 1,156 yards and six touchdown receptions. He is ranked third all-time in receptions (1,234) and yards receiving (15,545) and eighth in touchdown receptions (110).
