Michael Irvin says Aaron Rodgers' Week 1 struggles can be pinned on his offseason thoughts of quitting football ... telling TMZ Sports the QB's retirement talk played a role in his bad day against the Saints.
"This game is too hard," Irvin said at Dulles International Airport on Friday. "That's why you hear people say, if you're talking about or thinking about retiring, you're already retired."
