Shannon Sharpe went from seventh-round pick to All-World TE in 10 years with the Broncos. He left Denver for Baltimore in 2000 and helped the Ravens win a Super Bowl. In his two seasons as a Raven, he led them in receptions once. He also famously was part of a 96-yard touchdown play with Trent Dilfer in the 2000 AFC Championship Game. Another HOFer on the list.
