I just think with the PS rules, it's not as big of a deal. You can keep extra at a spot because you just deactivate them and call up those other positions that need a spot. Really, it's a 55-man roster now, with teams cutting players they feel they can get to the PS and call up (and a rotation of players for those two spots). It's kind of changed roster building a bit.
A player like Wheat, for instance, might have got a spot because Dallas felt if it cut him, Quinn would claim him. So instead it cuts Lawson and Muhammad because they were late additions to the roster (so you know they weren't in high demand) and are vets that can't be claimed. Teams are more apt now to keep players who can be claimed. Handshake deals can be reached with vets.
