CHICAGO (MCT) — Bears receiver Brandon Marshall, who publicly disclosed he received treatment for a mental illness, posted two videos online Monday in response to NFL Network analyst Warren Sapp calling him a “retard” on a radio program last week.

On the syndicated “The Dan Patrick Show,” the former Bucs and Raiders defensive end said, “These kids that play the game today have no relevance for the past, have no conscious of what it is. I mean, Brandon Marshall talking about Shannon Sharpe, who is he to talk? He’s the first 100-catch receiver, back-to-back, retard. What you just did in Denver for three years. You don’t know this? No, of course he doesn’t, because it’s not about Brandon Marshall ... it ain’t about the past, it’s about me. It’s about personal success, pay me, and now I’ll think about being a team guy.”
