Shane Waldron: Shane Waldron (born August 17, 1979 in Portland, Oregon) is an American football coach who is the current tight ends coach of the Los Angeles Rams of the National Football League (NFL).

Jimmie Giles: Jimmie Giles, Jr. (born November 8, 1954) is a former professional American football player who was drafted by the Houston Oilers in the third round of the 1977 NFL Draft.  A 6 ft , 238 lb tight end from Alcorn State University, Giles played in 13 NFL seasons from 1977 to 1989.  A four-time Pro Bowl selection, Giles's career flourished as a member of the Tampa Bay Buccaneers during the early and mid-1980s, despite being used mainly as a blocker during several seasons in which he fell into disfavor with the coaching staff.  Giles' benching coincided with a training-camp holdout, the first in Buccaneers history by a player under contract, and the difficult Doug Williams negotiations that resulted in his departure for the USFL.  Giles' four touchdowns against the Miami Dolphins on October 20, 1985, tied Earl Campbell's record for the most touchdowns by a Dolphins opponent, and is still (as of 2010) the Buccaneers' single-game record.  Dolphins coach Don Shula said of the performance, "I can't remember any tight end dominating us that way".  Buccaneer teammate Gerald Carter said that Giles could have been "one of the best all-time tight ends, if they'd used him more".  In 1988 with the Philadelphia Eagles, he caught a touchdown on one of the most memorable plays in Monday Night Football.  Quarterback Randall Cunningham escaped a tackle from Giants linebacker Carl Banks and threw a touchdown to Giles.
