I really don't think that's a good way to look at things. For starters, cutting Carp would yield $2.4M in cap space, but about that much would get spent on a new kicker anyway so there really wouldn't be a net gain. You can look at the KW situation similarly as a quality replacement would cost real money. But kickers are pretty interchangeable and comparable talent is easy to find. Quality DTs are a different story. IF the Bills are confident they can replace KW in FA with a younger player of similar ability, then they'd be better off doing that. Let's face it, KW is done after this season and it'd be much better to have a long term solution in place than to be scrambling to find one next offseason. Keeping him at a reduced salary this season while getting a rookie's feet wet is another good way to go.
