For the first time since 2011, quarterback Andrew Luck was not on the roster, as he announced his retirement on August 24, 2019. A four-time Pro Bowler and the top pick in the 2012 Draft, Luck led the Colts to four playoff appearances (2012–2014, 2018), an appearance in the AFC Championship Game in the 2014 season (the franchise's only time doing so in the post-Peyton Manning era), and won the NFL Comeback Player of the Year award in 2018. A four-year cycle of injuries and rehab that dated back to 2015 had "taken his joy of this game away," which led to his decision of retiring. This would also mark kicker Adam Vinatieri's last season in the NFL, after playing 24 years in the league, as he would spend the entire 2020 season in free agency before retiring on May 26, 2021. A four-time Super Bowl champion with the Colts and New England Patriots, Vinatieri is considered one of the greatest kickers of all time and made memorable game-winning plays with the Patriots in games such as the Tuck Rule Game and Super Bowls XXXVI and XXXVIII. Vinatieri was also the last remaining active player whose career began in the 1990s.
