3. Shannon Sharpe (Broncos/Ravens)
This guy was the original underdog. Taken in the 7th round of the 1990 NFL Draft, Shannon Sharpe was passed up a lot, and now those teams that passed him up sure do regret it. He was the younger brother of NFL great WR Sterling Sharpe, and that pair of brothers were extremely good at their respective positions. Shannon ended up with three 1000+ yard seasons on the way to retiring with the records for TD receptions, receptions, and receiving yards by a tight end, which would later be broken by Tony Gonzalez. He was the 1st tight end in NFL history to have 10,000 receiving yards in his career. Today, we know him as a wise-cracking analyst on CBS, where both he and his brother work at. He was inducted into the Pro Football Hall of Fame in 2011.
2. Kellen Winslow Sr. (Chargers)
He is the first great Chargers tight end, really the first great tight end in NFL history, and he was a tough one. He has played in above 100 degree and sub-zero weather, and this was in back to back weeks. The older Bengals fans will remember the Freezer Bowl, in which the Bengals hosted the Chargers in the coldest game in recent memory. Winslow was a giant part of that game. A lot of us remember his son, who had a pretty good NFL career himself. He is aleady in Canton, and has a legitimate argument for the all time greatest tight end.
