"He was a Pro Bowl center and was a member of what was regarded as the best offensive line in the NFL at the time," former NFL coach Chuck Knox said in a 2015 interview, via The Detroit News. 

"He was an outstanding center. He had been a wrestler in high school and college and had good balance. Plus, he was tough and smart."

He played two seasons with the San Diego Chargers before retiring. In 165 career games, Flanagan missed just one start — in his final NFL season.
