@RichardVeilleux there or anybody who knows about CFL Free Agency and negotiation lists? I'd post this in the CFL free agency thread rather, but no one is over there but me now.
It remains to be seen the aftermath of the NFL season with regards to just what happens and what does happen with the practice rosters. The NFL liberalized the rules such that many a veteran player, or I am not sure even if there are restrictions on veteran status any more right now, can be on them.
The NFL seems wise to do so in case some team gets hit with an epidemic of cases, for then they have even better players at hand than usual from practice rosters.
These are all guys not good enough to make a team yet likely out of football, waiting for injuries late in the season and keeping in shape, for their long-shot chance. And many more now have ample NFL experience in having made at least one team.
A small few of these guys look like CFL material the best I can guess, and I have posted a few key names above for mostly offensive players.
