John Parker Wilson

Freshman season

After helping lead Hoover High School to high school state championships in 2002 and 2003, Wilson accepted a scholarship offer to play for the Alabama Crimson Tide. At the time, he also had scholarship offers from several Southeastern Conference schools, including Alabama's rival, Tennessee. He saw limited playing time during his freshman year, backing up full-time starter Brodie Croyle. His first career touchdown came against South Carolina, a 36-yard pass to wide receiver Keith Brown, in Alabama's 37–14 rout of the Gamecocks. He would finish the season with only 98 yards and two touchdowns.

Sophomore season

In 2006, Wilson started all 12 games for the Crimson Tide. He finished the season with a passing efficiency of 128.92, completing 216–of–379 passes for 2,707 yards, 17 touchdowns, and ten interceptions. He threw for over 200 yards in the first seven games of the season, setting a new school record, and finished with a school record nine 200-yard games.

Junior season

In 2007, Wilson started 13 games for Alabama. His passer rating was 114.6, completing 255–of–462 passes for 2,846 yards, 18 touchdowns (a school record) and 12 interceptions. He was sacked 25 times during the season. His best performance was against rival Tennessee, in which he completed 32 of 46 passing attempts for 367 yards and three touchdowns. Another notable performance was his winning touchdown against Arkansas with eight seconds left in the game.

Senior season

In his senior season, Wilson was again the starting quarterback, ahead of Greg McElroy. He led the Crimson Tide to a 12–2 season, with victories against #9 Clemson Tigers, #3 Georgia Bulldogs, and #15 LSU Tigers. In the regular season finale, he led Alabama to 36–0 victory over in-state rival Auburn in the Iron Bowl, ending a six-game losing streak to the Tigers. After finishing the regular season 12–0, #1 Alabama eventually lost to #2 Florida in the SEC Championship Game. In the 2009 Sugar Bowl, Alabama was defeated by the Utah Utes by a score of 31–17.

When his career at Alabama ended, Wilson held every significant passing record in Alabama school history.

Atlanta Falcons

Wilson was signed by the Atlanta Falcons after going undrafted in the 2009 NFL Draft. He did not play in any regular season games. Wilson played most of the game during the 2010 preseason game against the New England Patriots. He assisted in scoring one touchdown during that game. He was released during final cuts on September 3, 2011, and re-signed to the Falcons' practice squad the following day. On December 2, 2011, it was reported that the Vikings tried to sign Wilson off of the Falcons practice squad. Instead, Wilson chose to sign to the Falcons' 53 man roster. On August 26, 2012, he was waived by the Falcons in order for the team to maintain a league mandatory 75-man roster during the preseason.

Jacksonville Jaguars

Wilson was signed to the Jacksonville Jaguars practice squad on September 1, 2012. He was promoted to the active roster on October 27 and released on October 29. He was signed back to the practice squad on October 31. Wilson was signed to the active roster after the conclusion of the 2012 season. He was released by the team on February 27, 2013.

Pittsburgh Steelers

One day after being released by the Jacksonville Jaguars, the Pittsburgh Steelers claimed Wilson off of waivers. The Steelers were the only NFL franchise to make a claim for Wilson. Wilson was later released by the Steelers on August 25, 2013.

After his time with the Steelers, Wilson did not sign with another NFL team.
