I don’t think they have equal blame, but I think there’s something to this.
I understand a GM shouldn’t meddle as a rule, but there were issues and trends seen by the yeomen on here that Walters, or any ops staff in the pros, should have been able to mitigate sooner. Letting all the top-end talent get into their mid-30s at the same time is a fail.
If MOS doesn’t want to use more impactful players, why is the option still being given to him? Why were Kyrie Wilson, Jake Thomas, BA etc even offered spots to compete? That last grey cup game alone should have been the wake-up call to Walters.
At a certain point, one guy is there to provide the best on-field talent possible, the other is there to use the talent provided to win football games.
If the coaching staff is undermining that, the GM has to make the tougher calls. Imo, Walters isn’t completely blameless in that context.
