"He ought to be happy he's in Cleveland making a nice dollar and they want him there," the Steelers legend says.
Odell made serious headlines Monday after he went scorched earth on the G-Men in a new GQ article ... ripping his old squad for trading him to Cleveland this offseason.
"I felt disrespected, because I felt like I was a main reason at keeping that brand alive," Odell said.
