Jarry is the way to go. Big-money, long-term contracts for goaltenders almost never work out. Name the last goaltender signed to a 6+ year deal where the team was still happy with the contract in the final few seasons. Rask, Rinne maybe?....that's about it. Even goaltenders that look to be can't miss contracts (Price, Quick, Bobrovsky), end up looking like bad decisions only a few seasons later.

Trade Murray, get a few good seasons out of Jarry, then trade Jarry and continue forward with whoever the next young goaltender is.

As soon as I saw that you had signed Gudas I quit reading.
