Letroy Shelton Guion Jr. (pronounced /ˈɡaɪən/ GHY-ən; born June 21, 1987) is a former American football defensive tackle. He played college football at Florida State. Guion was drafted by the Minnesota Vikings in the fifth round of the 2008 NFL Draft. Guion also played for the Green Bay Packers.

Guion attended Bradford High School in Starke, Florida, and was a student, basketball, shot put and discus thrower, as well as a standout football player. In football, he played on the varsity team for four years while starting three and helped lead his team to the state semifinals in each of his last three years. In both his junior and senior season he was an all-state first-team and all-area selection. As a senior, he totaled 131 tackles, 21 tackles for minus yardage, 12 sacks, and forced 11 fumbles.

He chose Florida State over Georgia, Tennessee, and Iowa.^[1]

In his true freshman year at Florida State, Guion appeared in ten games as a back-up defensive tackle, and totaled 10 tackles and one quarterback hurry on the season. Five of those, including 1.5 for loss, came in his only start of the season, when he replaced Andre Fluellen against The Citadel. Guion was the only true freshman to earn a start on defense during the 2005 season.

As a sophomore, Guion played in 12 of the Seminoles' 13 games and started five games (Virginia, Wake Forest, Western Michigan, Florida, UCLA) at defensive tackle. He finished 11th on the team with a career-high 25 tackles including a career-high four tackles for minus yardage. 24 of his 25 tackles came in the final seven games.

As a junior, Guion earned eight midseason starting assignments at left defensive tackle, replacing an injured Fluellen in the lineup. He finished ninth on the team with 31 tackles (17 solos), including a sack and 6.5 stops behind the line of scrimmage. He also broke up one pass and recovered two fumbles. Guion missed the Music City Bowl due to suspension; he was part of the school's academic cheating scandal that saw 36 football players ruled ineligible for postseason action.^[2][3]

After starting just 14 games during his three years with the Seminoles, Guion announced that he would forgo his senior season and declare for the 2008 NFL Draft.^[4] Described as “a solid developmental prospect who should get consideration in the late rounds” by Sports Illustrated, Guion was projected to be a middle-seventh round pick.^[5]

Guion is a cousin of former Buffalo Bills linebacker Sam Barrington.^[17]

At 11:00 PM on February 3, 2015, Guion was driving in Starke, Florida when he was pulled over by police after his vehicle was observed to not be staying in its lane properly. It was discovered that Guion was in possession of 357 grams of marijuana, $190,000 in cash, and a 9mm semi-automatic handgun.^[18]

On March 24, 2015, Guion reached a plea deal. It included a $5,000 fine plus court costs. Since Guion had no prior record, the charges were dismissed without adjudication of guilt.^[19]

On June 21, 2017, Guion was arrested in Waikiki, Hawaii for operating a vehicle under the influence of an intoxicant. He was released from jail on a $500 bond.^[20]
