Michael was reminiscing about his time as a pro footballer
Chatting to ET, Michael – who discussed his HBCU education –credited this experience for making him adaptable.
He said: "When it comes to daytime television when it comes to the news, it is intimidating, it is scary at times because these are things I didn't necessarily go to school for.
"These are things that I wasn't necessarily groomed to do… I've learned to adapt. I learned to adapt at TSU… I try to be the best that I can be, so I can be an example for those who are falling behind."

Michael added that he initially found his GMA responsibilities to be "the scariest, most intimidating, hardest thing I've ever done in television," but is proud of how his career has turned around.
He said: "It's not something that is natural in a lot of ways… I had to learn it's not my job to necessarily be the personality. It's not my job to take it wherever you want to take it… Most of all I have to listen.
"It took me a while to learn that, but now to be given that responsibility… I don't take it lightly."
