There are 134 guys who average 18:26 a night (that's effectively my top 4 cutoff)- though injuries, tenure, team depth all play a role. My first cut off guy was Zub, who'd be our top pairing RHD. Lilji and Fabbro were 7th dmen, now they are top 4. Here are those drafted in the past 10 years (Zub also was undrafted!)
'22: Hutson, Mintuykov
'21: Power, Edvinsson, Evans, Moser, Zellweger, L. Hughes, Clarke
'20: Faber, Sanderson, Guhle, Drysdale, Andre
'19: Seider, Vlasic, Byram, York, Harley, Broberg, Lacombe
'18: Hughes, Dahlin, Dobson, Bouchard, Bahl, Romanov, K'Andre Miller, Durzi, Kesselring, Fehervary, Sandin
'17: Makar, Heiskanen, Anderson, Ferraro, Samberg, Kovacevic, Liljigren
'16: Sergachev, McAvoy, Hronek, Fox, Girard, Chychrun, Lindgren, Fabbro
'15: Werenski, Anderson, Provorov, Gavrikov, Chabot, Hanafin, Dunn, Carrier, Mikkola, Roy, Carlo, Cernak, Lauzon
Aside from the very best, these guys probably aren't long term options for SJ's window
'14: Sanheim, Montor, Toews, Ekblad, Forsling, Walman, Petterson, Middleton
'13: Jones, Morrisey, Weeger, Pulock, Theodore, Pesce, Nurse, Risto, Zadorov, Soucy
'12: Parayko, Mattheson, Ceci, Severson, Lindell, Slavin, McCabe, Skjei, Reilly, Lindholm, Pelech, Trouba, Grelyzck, Maata, Kulak, GhostBear
Finding top 4 d-men (or at least top 4 fill-in capable) isn't impossible. I'd bet on Grier grabbing another this summer. Walman, Ceci, Liljigren, Fabbro, Durzi, Moser, Sergachev, Broberg, Carrier, Roy, Pesce, Skjei, Zadorov, Montour, and Bahl have moved this year. None of those guys are #1 (maybe not even #2). However, all but Fabbro would be in our top 4 (and he may very well beat Lilly/Ceci out).
Getting #1 or top pairing guys is way, way harder. I'd be watching Miller, Dobson, Bouchard, Sanderson, Power, McAvoy, and Dahlin if any shake loose (I'd bet less than 1.5 move in the next 3 years). Jiricek was interesting as top pairing RHD with size and skill is our largest org asset gap. Grier could have cleanly beat Guerin's offer. The fact he did not, tells me we projected him as a 2nd pair guy, still worth having, but not worth outbuying for.
If you get Schaefer, and he & BDE both hit 80% of their ceilings, you can probably make do with #4/5 physical RHD filling out your top 4 for the next 15 years. One more pick invested in D likely results in C, D, G is likely solved for the next decade. You could have every prospect winger not on the roster miss and still be on your way to being a contender.
Don't get me wrong, I want Moorehouse and Grier taking the player they think is the best, but all things being equal, a future #1 Dman is the biggest hole.
