Unlike the sometimes-bloated staffing in the NFL, where multiple coaches often oversee one position, CFL teams have a more condensed approach when it comes to coaching. Toronto, however, is pretty thin on the defensive staff, even by league standards, with just three coaches on that side of the fence.
Returning to Toronto's defensive staff from 2023 is respected longtime Argonaut Eiben (linebackers) and one of the league's top assistants in Fields (defensive backs). Former Toronto player and CFL lifer Demetrious "D-Max" Maxie will join the two returnees as defensive line coach, returning to the organization for which he starred.
