Or usurp the job of those above him, which is why he might not get hired.
You can't blame a guy for seeking promotions. A position coach is worth enough to be comparable to any position in the CFL and it presents promotional opportunities. If you can become a Coordinator in the NFL, ala Mark Trestman, it's a massive promotion financially that any reasonable person should want to take. Let's not even mention what being a head coach would mean. A man has to do what's best for his family. Moving back to your native country and for a big payday is a honest decision for a man to make even if it's inconvenient for CFL teams to accept.
Chris Jones is a very good coach and I for one really enjoyed watching the team in the years he coached. I'd be happy to see if he can repeat his previous success even if it's a short term arrangement. Winning is what matter most and that's what he does. A good QB with his D is a recipe for success IMO.
