The Oilers are looking for improvements to their bottom six still. Holland is expected to go after someone as a UFA for that purpose. Ritchie would be a welcome addition, bumping Shore off the 4th line.
If Holland can find a trading partner for Kassian and his $3.2 Million dollar contract, say for a 5th or 6th, he'd have room to add Ritchie and maybe even Kase as a RW, moving Yamamoto or Puljujarvi out of the top six and Archibald to the 4th line. Just a thought.
