Passage 2: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 , 238lb 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 2017) the Buccaneers' single-game record; despite this, the Dolphins would win 41-38. 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.

Later, he participated in the preparation of the Greek War of Independence in Messenia and when that begun, he was at the side of Theodoros Kolokotronis, whom he followed in the military operations in Arcadia. Despite his advanced age, he participated in the Battle of Valtetsi in May 1821 as the head of the fighters of Androusa and Leontari. Positioned on the western bastion of the Greek camp together with Ioannis Mavromichalis, P. Kefalas and Dimitrios Papatsonis, he was distinguished for the repulse of the repeated attacks of the Ottoman cavalry. Later he participated in the siege and conquest of Tripolitsa. In 1822, he participated in the operations against the expeditionary force of Mahmud Dramali Pasha. For his contribution, he was named a chiliarch in 1823. During the Greek civil wars of 182425, he supported Kolokotronis's side and for that, he was arrested and jailed by the government forces of the Georgios Kountouriotis in the monastery of Prophet Elias on Hydra Island. Soon after his release in May 1825, he became a general and took part in the operations against Ibrahim Pasha of Egypt.
