There will never be another
Some of the CFLs older records are super impressive
Back in those days the level was much closer to NFL (who really did not become dominant until 80s; in 70s CFL still had some major talent and even USFL fielded some teams that could certainly beat the NFL back in the 80s)
Now with the insane $$$$ NFL throws around (I am still baffled by amount networks + ads pays) they can sign CFL all-stars to sit on the bench
to me, the closest RB the CFL ever had to Barry Sanders was Clemons.
