Early years

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.

College career

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.

In his junior year, 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.

Professional career

He finished the 2014 season with a career high 3.5 sacks, 32 tackles, two forced fumbles and one batted pass. Packers coach Mike McCarthy spoke highly of Guion after the week 17 victory over the Lions. "I think Letroy has been everything we thought he was going to be. I've always had a lot of respect for Letroy in Minnesota. I think he's come over to us, and I think he's taken his game up a notch. He's an excellent fit in the locker room, teammates love him, he's an excellent teammate, and he's a damn good football player."

2015 arrest

At 11:00PM 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.
