You have Winnipeg confused with Hamilton. Our bench strength last year was the BEST in the league at every position except quarterback and kicker. The only thing that could've stopped us was an injury bug the size of Saskatchewan's. They had 21 guys in the infirmary and counting as they headed into the latter part of the season.
Hamilton on the other hand couldn't afford much in the way of backup help since their starters were overpriced. Once they dump either Masoli or Evans and move on from some of their aging linemen they'll magically rise to the top of the standings again. It's amazing what a team can achieve with younger players and more cap space.
If the Lions can somehow renegotiate Reilly's contract down a notch or two (and don't say it can't be done... Hufnagel did just THAT with BLM's contract today) then maybe they'll be able to build a better team.
