Toronto defensive coordinator Corey Chamblin decided against interviewing for the Alouettes head coaching job, per sources.

Montreal had received permission to meet with Chamblin who coached the Argos defence to a Grey Cup championship.

Chamblin inked a two-year contract with the Argonauts before the 2017 season which runs through 2018.

Chamblin has turned around the Argos defence that ranked last in points allowed (568), touchdowns allowed (59), rushing majors (19), rushing yards allowed (2,074), yards per rush (5.7), yards per completion (8.7), opponent completion percentage (70.9), red zone chances allowed (62), big plays allowed (rushes 20-plus yards and completions 30-plus yards equaled 52) in 2016.

Compare those numbers to Toronto’s defence in 2017. The Argos rank in the top five in points allowed (443), opponent touchdowns (46), passing touchdowns allowed (25), opponent net offence per game (second 337.2), opposition yards per play (6.2), two-and-outs (65), sacks (second 47), rushing yards allowed (1,454), passing yards allowed (4,654), opponent completion percentage (second 64.8) and opponent QB rating (70.3).

Chamblin was a defensive back in the NFL from 1999-2004. After that, the 40-year-old rose through the ranks in the CFL becoming a head coach for Saskatchewan in 2012. He led the Riders to a Grey Cup triumph on prairie soil in 2013, earning the franchise just its fourth, and most recent, 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. All those post-season victories came in the most memorable run in Saskatchewan sports history which saw the Riders claim the Grey Cup at Taylor Field with a dominant win against Hamilton 45-23.
