Former Broncos safety John Lynch says that teams should be wary of trading for receiver Brandon Marshall. Lynch was Marshall's teammate during the 2006 and 2007 seasons in Denver. "I don't like saying [buyer beware], but you've got to call a spade a spade, and I think it's a dangerous proposition," Lynch said. "I don't think you'll see the Broncos sign him to a long-term deal, because right now the behavior he's demonstrated off the field, I don't think you'd feel comfortable doing anything long term. "As I said, on the field, he's very comparable to a guy like Terrell Owens. He's that good of a player. But being a professional in my mind ... takes doing it on the field and off the field. You can't have all choir boys. I believe in first and second chances, but when you're talking about 13 or 14 ... I think at a certain point you've got to say this guy's got some issues that he's got to work out before you can trust him."
