The Toronto Argonauts have relieved Corey Chamblin of head coach duties, per sources.

The Argos’ season ended on November 2 in Hamilton, which means it took over a month to make the final decision, but general manager Pinball Clemons wanted to be diligent. Chamblin signed a three-year contract last December.

2019 was Chamblin’s first season at the helm of the Argos and Toronto finished out of the playoffs. The Argonauts had the second-worst record in the league at 4-14. Chamblin specializes in defence, but Toronto gave up a league-worst 29.9 defensive points per game. The year started by allowing 64 points in a 50-point blowout loss to Hamilton.

Chamblin was the Argos’ defensive coordinator during the Grey Cup-winning 2017 season. That Argos defence was stout under Chamblin, but sunk to the bottom of the league in 2018 while he worked at the University of Arkansas.

Toronto allowed the most points (560) – the only team to allow more than 30 per game – while giving up a league-high 35 touchdown passes, recording the lowest amount of sacks (24) and forcing the least amount of turnovers (26).

The 42-year-old coach bench boss has a championship on his resume. Chamblin led the Saskatchewan Roughriders to a Grey Cup triumph on prairie soil in 2013, earning the franchise just its fourth CFL title since being established in 1910. During three-and-a-half seasons as head coach in Riderville, Chamblin posted a 29-34 regular season record while going 3-2 in the playoffs.

Chamblin ends his tenure as bench boss in double blue after just one season.
