3 released and Armour retires??? Damn, I'm really surprised they simply released Smart. We should have traded him, I hate seeing players go for nothing.
You can be sure trades are attempted for any and all players, but it seems trades are still rare in the CFL when a team can just hang-on and wait for someone to be released outright. The exceptions seem to be for up-and-coming non-imports swapped for imports that fill a very specific need.
