While Johnny Unitas is worthy of praise for his record-setting quarterback performances, three NFL Most Valuable Player honors, and being just all around bad a**, we still have to give Peyton Manning the throne for the greatest Colt of all-time. Honestly, there is no better predecessor for Peyton Manning to have than 'The Golden Arm' Johnny Unitas himself. Watching Peyton Manning play there's just a fearlessness about him. Maybe because he was extremely calculated and prepared at all times or maybe the football gods were just on his side throughout his Hall of Fame career.
After breaking the SEC record for career wins at the University of Tennesse, the first son of Archie Manning was drafted 1st overall by the Indianapolis Colts where he would play fourteen seasons of his eighteen year career. Throughout his illustrious career, Manning has led the league in passing touchdowns four times, passing yards three times, and passer rating three times. Not to mention he's been selected as NFL MVP five times and led the Colts to victory in Super Bowl XLI. We haven't seen such a maniacially studious quarterback in the league since Manning retired in 2015.
