This is a good problem to have.
If we want to protect Mayfield from waivers we can send Pelech down for the balance, he is exempt this year. He has earned a spot but numbers could squeeze him out until after the expansion draft.
We could expose CDH and/or Hickey, and if I am not wrong also Pulock is eligible to be taken. Before we get there, Snow can engineer a trade of one of Hammer, CDH, Hickey, Pulock, Seidenberg.
We need 8 NHL defensemen. We don't need 3 goaltenders, one of which takes up a roster spot.
We need to continue to test Mayfield in games conditions to get comfortable that he can handle a regular spot.
