Another terrific signing by Fitzgerald, and there can be really no disputing this if only because of the contract terms.
I've been watching Kulikov for years, and he's a very good defenseman, when healthy. The "when healthy" would be a huge concern were the Devils a Stanley Cup hopeful or if they had just signed him to a four-year, $16 million deal. But at 1 year, $1.5 million? The Devils have essentially picked up a big, mobile, smart, physical and capable left defender on not much more than a "prove it" deal. The Devils went into the 2020 off-season with Will Butcher as their top LD on the depth chart. With the addition of two superior defenders in Ryan Murray (acquired for a 5th round pick) and Dmitri Kulikov (acquired for what amounts to "petty cash"), the Devils are no longer a complete liability on LD.
It certainly bears noting that both Murray and Kulikov have had trouble staying healthy over their careers, and the Devils could certainly benefit by adding one more player to provide stability and depth for the left side of the blueline (I would strongly recommend a one-year deal to a familiar face in Andy Greene).
Best case scenario? The Devils have rid themselves of an abominably bad coach in John Hynes, while solidifying their biggest concerns in goal with Crawford, and on LD with Kulikov and Murray. Though the Devils are far from a pre-season favorite, if they are healthy and get expected production leaps from young studs like Hischier, Hughes and Bratt (also Smith), they can challenge for one of the lower playoff spots.
But it's actually the worst case scenario which makes the Kulikov (and Murray) acquisitions so shrewd. If the Devils are heading towards the lottery at the trade deadline, capable NHL defenders like Kulikov and Murray are annually in demand at that time. If healthy, these are certainly players who can garner the Devils a second or third round pick.
Like the Murray trade and the Crawford signing, the Kulikov signing makes the Devils stronger now and potentially stronger in the future. Kudos once more to Mr. Fitzgerald.
