Yeah I get that but Mittelstadt is making $2.5M this year. They could fit him in right now...use him for the playoff run and as an RFA, even though this is unlikely, they could even turn around and trade him at the frikkin' draft if they can't come to an agreement on a long-term contract.
I completely understand their thinking "well, we've got Ritchie coming" but in my opinion - that is a mistake, one that they've made in the past with Jost & Newhook.
Don't bank on a young prospect taking the league by storm at age 19,20,21 - if it happens, great - that's a nice problem to have. You have to live in the NOW just like your competitors are...the ones who keep making bold and aggressive moves.
The Avs cannot let their fears of being up against the cap because - Landy is for sure coming back 100% or some shit like that - stop them from being aggressive and giving themselves the best possible chance to win. Even if the odds on Landy coming back healthy for the rest of his contract are 50% which I think would be very high, you still have to proceed as if he's going to be on LTIRetirement as you move forward. You roll the dice and if it happens, then you probably have no choice but to trade Rantanen anyways.
