They are probably three years out from being a serious contender. Eichel, ROR, Samson should be a center spine for years to come.
Nylander is 1.5 years away, probably, from contributing. Risto is likely a #1 defenseman. He needs fewer minutes and help. McCabe is a first or second pair D.
The new fellas brought in on D should at least constitute an average blue line, which is a big step up from last year. Housley's system of puck possession should benefit the offense. GMTM made some mistakes, but he was nowhere near the disaster you habitually depict.
