Broncos' wide receiver Brandon Marshall has fired back at Dolphins' linebacker Joey Porter, calling him insecure. "Yeah, Joey Porter's one of them guys, when you got guys who talk a lot of trash, just want to talk about people or put people down, they have their own insecurities," Marshall said. "And his insecurities I don't know. But he's definitely one of those guys who all those muscles are popcorn muscles. He's soft." Porter called Marshall soft after the Dolphins' 26-17 win at Denver on Sunday.
