Well that’s true when UFL camps opened up in the last few days, but there have been a few players who have moved from prior NFL (usually just practice rosters and camps, occasionally seeing real game time) and/or UFL experience who opted for the CFL in the preceding months.
There have been quite a few tracked in another thread and beyond, and irrespective of the UFL, I figure in the coming weeks there will be quite a few more of those players who are not even opting to go to UFL camps at all.
