They are making the mistake of including old contract into the mix to say the Skywest captains are at industry scale. Contracts are about the future, not a combination of the present (Endeavor and Envoy) and the past (TSA, GJ, Compass, and all the others).
Skywest needs to pay more than Endeavour or Envoy. Skywest needs to pay more for not having a flow through. Skywest needs to pay more for not having mainline travel benefits.
