Apologies Snives if my commentary was not crystal clear, but my comments regarding the limited NHL prospects for late round draft picks was directed mostly at
the way things stand at present, and in the last decade or so of NCAA-to-NHL progressions. But I think your listing of (especially) the older late round picks from the Holt/Umile Eras allows us to also show that late UNH picks during those olden days still had a shot at making it, and the current late UNH picks are not faring as well. Coach Holt had an exceptional reputation as a teacher, and Coach Umile's players would also progress during their time on campus, if not quite with the same frequency as Coach Holt's players. Further grist for the "MS7 isn't developing his players during their time under his oversight".
Let me go through some of the late rounders you've cited to make my point (rarity of NHL "hits") and the secondary point that Holt/Umile knew how to teach:
Bobby Gould (7) - this will start to sound repetitive, but Bob (#17 scoring at 17:17 of the 3rd period in the '79 ECAC title game) was the best player by far in his draft year round, which included 1980 Olympians Bob Suter and Ralph Cox. His #118 draft slot today would be a late 4th rounder; best non-G #118 pick ever.

Jamie Hislop (8) - the 140th pick in his NHL Draft year, second highest goal scorer of all #140 picks ever (and #1 if his WHA goals are counted). #140 would be a fifth round pick these days. Only guy with more top tier pro games was PHI enforcer Dave Brown. 'Slop would have played longer but for an eye injury.

Daniel Winnik (9) - best player ever drafted at the #265 slot in NHL history, and one of three (3) players in his draft round to qualify for full NHLPA pension. Also falling in that round 21 years ago was a certain Craig Switzer, who landed in the Coast with 3 games in the AHL for likely injury call-ups ...

Sean Collins (9) - no player has ever been drafted at #289 and ever played a single game in the NHL. Collins' career arc not at all unlike that of Craig Switzer (above). Michael Hutchins and Ned Havern (BC) were others picked in the same round who didn't Show. Only Jonathan Ericsson (DRW) was pension eligible.

Bruce Crowder (9) - his draft slot (#153) would be a 5th rounder in the present-day NHL Draft. By far the most successful of players drafted in his draft year, same round. Second-best player ever drafted at #153 behind another familiar name for locals, Craig MacTavish. Left a flagging NHL career to coach at UMO.

Andy Brickley (10) - his draft slot of #210 would be a 7th rounder in the present-day NHL Draft. Literally the last player drafted in his draft class, and was also the most successful player taken in his round. "Only" the 3rd best player taken at #210, behind two stiffs named Dave Taylor and Henrik Zetterberg.

Dave Lumley (12) - his draft slot of #199 would be a 7th rounder today. The best (and only) player from his draft year's round to make it to the WHA and the NHL, won two Cup rings while at EDM. "Only" the 3rd best player taken at #199, not far off Willie Mitchell, but eons removed from Dominik Hasek

Players like these no longer frequent UNH line-ups during the Souza Era. Angus Crookshank (5th round pick 2018) has scored 2 goals in 20 NHL games, and will be 26 at the start of next season. He is your high water mark of post-Umile excellence. Shane Eiserman (4th/2014), Marcus Vela (7th/2015), Max Gildon (3rd/2017), Benton Maass (6th/2017), Mike Robinson (3rd/2015), Filip Engaras (6th/2020), Luke Reid (6th/2020), and Harrison Blaisdell (5th round/2019) are most but not all of the total draftees over the last 10 seasons who have (at least to date) come up short of The Show.
So kudos to Snives for making a case that late round picks playing at UNH haven't always regularly fallen short of the NHL. But they do now. And now counts.
