Nelson Martin is the club's defensive backs coach and Mike Scheper will be the defensive line coach. All three have recent experience with the Saskatchewan Roughriders, the team announced Thursday.
Etcheverry last coached in the CFL with Saskatchewan, leading their defence to back-to-back Grey Cup appearances in 2009 and 2010. He was head coach of the Toronto Argonauts in 2002 and defensive co-ordinator of the 2004 Ottawa Renegades.
Most recently he was head coach of the University of Ottawa Gee-Gees. Etcheverry has previous coaching experience in the NFL, German Football League, CIS, Canada Junior Football League and NCAA.
Martin spent the 2012 season as Hamilton's defensive backs coach and before that held a similar post with Saskatchewan for two seasons. He made his CFL coaching debut with the Ottawa Renegades in 2003 as a special teams assistant.
Scheper coached the defensive line at Portland State University the past two seasons and served in that capacity with Saskatchewan in 2009 and 2010.
