In his rookie season in 2017, Alexander was the team's nominee for the most outstanding rookie in the CFL.[2] Alexander won the 107th Grey Cup with the Blue Bombers when they defeated the Hamilton Tiger-Cats 33–12.[3] He had an interception early in that game when he grabbed Dane Evans' first pass of the game, this was one of seven turnovers created by Winnipeg.[3]
Alexander signed a one-year contract extension with the Winnipeg Blue Bombers on January 11, 2021.[4] Throughout the season, Alexander continued to build his reputation as a hard hitting safety for the Blue Bombers, with several bone crunching hits delivered to his opponents. While being named both a CFL West All-Star and CFL All-Star at safety for the first time, Alexander helped rebuild the Blue Bombers' secondary and recorded 36 tackles, two interceptions and one forced fumble as part of a defence that allowed a league-low 12.9 points per game.[5] In his second CFL season, Alexander competed in his second championships when the team went to the 108th Grey Cup against the hometown Hamilton Tiger-Cats. The Bombers would trail for much of the second, third, and fourth quarters. Alexander would go on to contribute two tackles in a tough battle as the Bombers would go on to win their second consecutive Grey Cup in overtime by a score of 33–25.[6]
