It makes sense for a team like the Bills to plug holes and acquire depth by signing vets who are willing to give up a little salary in exchange for a shot at a ring. We're going to have a rotating crew of guys like that around for the foreseeable future. It's fine.
We have a very good young core -- Allen (obv), Davis, Knox, Diggs, Oliver, Groot, Milano, Edmunds, Tre. Those guys and a handful of other guys are folks we can build around for the next handful of seasons. As long as we've got youth and talent among playmakers where it counts, I don't care how old our backup linemen is, or how old our gunners are.
