You can say I'm insensitive if you want, but sport is a business, and the Bulldogs need every advantage they can get.
He is a waste of cap space.
Yes, every player gets injured, but some more often than others. It's not always bad luck, there are genetic factors at play. Stanley's inclusion causes disruptions on the field when he gets injured mid-game, and takes up cap space in rehab. His brothers have had similar injury issues.
Stanley was a fringe player even when fit. All factored combined, he's a waste of cap space.
