The Als have hired William Fields as Assistant DB coach.

The Montreal Alouettes announced on Wednesday that the club has added William Fields to its coaching staff. The 37-year-old will tackle the roles of Assistant Defensive Backs Coach and Defensive Quality Control Coach.
Fields, who played for six seasons in the CFL, made his coaching debut in the Canadian circuit in 2015 as he was the BC Lions Assistant Defensive Backs Coach and Defensive Quality Control Coach. The McKeesport, PA native saw his protégés finish tied for second place in the League with 23 interceptions, including a league-leading six that belonged to defensive back Ryan Philips.
