Yeah this isn't cutthroat at all. Those same people crying about cowboys screwing him would be calling them incompetent if they had to continue paying him this year and further for a player that can't walk (*cough cough Crawford)
It's a team game with a cap so nothing bad about cutting players (welcome to business, if you can't perform at your job or someone younger can do it better for cheaper then in the real world you have a target on your back).
Injured players eating up the cap if anything hurts other players chances of winning (funny how that narrative never gets thrown around, it's always the other narrative of "owners screwing players and not honoring contracts").
