What do a few Super Bowl champion Broncos think about the current team? Not much, just like the crowd at Mile High Thursday night, which booed the Broncos off the field. Mark Schlereth, Shannon Sharpe and Ray Crockett — three key members of Denver’s back-to-back championship teams in 1997 and 1998 — went off on the Broncos on Twitter Thursday night, as the team was on its way to a 2-5 start thanks to a 30-6 drubbing by the Kansas City Chiefs. Schlereth, a former Pro Bowl guard for the Broncos, sympathized with suffering fans.
