Marve is safe at this point. Being the #4 going in, the expectation on him is the least but exceeded that with his performance last night.
Brohm, will get the benefit of being a McManus guy, from his time with the Cats to here. And considering that we burn a 2015 4th rounder on him he will not go anywhere.
Hall might remain #2 for now but as soon as Marve and Brohm gain some CFL experience. His job security will slowly disappear.
