Evans said Suh was "uncontrollable" and was late to team meetings.
"The consistent message that came out of there is that Suh was uncontrollable and that he would constantly do things to kind of show his power over Jim Schwartz, whether it was team meetings, showing up late or whatever it may be," Evans told 105.1 FM in Detroit on Friday.
On Sunday, Schwartz responded through a statement given by the Lions. He was hired as Buffalo's defensive coordinator last month. He addressed the lateness portion of what Evans said, but not anything about Suh exerting dominance over the former head coach.
"Ndamukong Suh was not late for any team meeting, practice or team travel in any of our four years together with the Lions," Schwartz said. "Anyone who reports otherwise is either being untruthful or has been misled."
Suh has one season left on his contract and both general manager Martin Mayhew and team president Tom Lewand have said they would like to sign Suh to a long-term extension.
