As far as I know, Rourke is making the basic low end entry salary. That is one reason BC could pick up and pay good players. Next season will be a different story and the Lions will have to pay him much more. Now the SMS will make keeping other high end players questionable.
Rourke will earn much more on his next contract, instead of employing 4 high-end vet. receivers the Lions will have to drop back to 2 or 3 and find a couple of middle of the road possession receivers or rookies as replacements. Not a big deal and not unlike what every other CFL team faces on almost a yearly basis. A receiver like Wolitarsky could fit in well on almost any team and wouldn't be a liability. Speaking of which Petermann is currently listed on their roster as a backup to Cottoy.
Rourke being Natl. also allows the Lions to employ 3 imports on the O-line which helps resolve a problem area they've had for many years.
