The PR is quietly solving Winnipeg's ratio math, not just storing bodies

Since Week 6, the Bombers have kept at least six nationals on the 10-man practice roster every single week, and four of them — Kyle Borsa, Tanner Cadwallader, Cole Adamson, Jeremy Murphy — have been elevated at least twice. That pipeline is what lets them dress seven national starters without burning a game-day spot on a dedicated fullback. Most teams treat the PR as injury insurance; Winnipeg treats it as a ratio hedge.
