It was a mere two years ago that Michael Smith was one of the franchise faces of ESPN. He and his tag-team partner, Jemele Hill, had matching four-year, $10 million contracts and were out front on what was supposed to be a fresher, hipper 6 p.m. “SportsCenter.” Today, Smith is in a gold-plated purgatory, nearly ostracized by ESPN. He is rarely on-air and, according to sources, there is no current plan for his final two years at the network.
