If you’re using them as examples of goalies returning decent value, that’s totally fine.
If you think Georgiev is comparable value wise, I’m not so sure. His numbers in the NHL aren’t comparable to those three who at the time were thought to be sure fire NHL starters. Georgiev would be targeted to someone looking for a backup or prospect and not a current starter. He definitely has some value and potential but I don’t think he’ll return a first. Maybe a struggling former first round pick or a second. But not a first(maybe a really late one, but it feels like a stretch)
Lehner played 86 career games for Ottawa prior to the trade in June 2015. He was about 1 month from turning 24. The bulk of those games were played in the 2 years prior:
2013-14: 36 games, 3.06 GAA, .913 SV%
2014-15: 25 games, 3.02 GAA, .905 SV%
Georgiev has played 63 career games. He is 1 month from turning 24. His numbers this year and last:
2018-19: 33 games, 2.91 GAA, .914 SV%
2019-20: 20 games, 3.17 GAA, .909 SV%
They are very comparable. Add to that the fact that Anderson's numbers in 2014-15 (2.49/.923) were significantly better than Lehner's, so it's not just a case of playing behind a bad defense, and he still returned the 21st overall pick. To be fair, Legwand was part of the deal also, but his value wasn't that high.
Jones had better numbers, but he had played less games (34 total), and he was 25 at the time he was traded:
2013-14: 19 games, 1.81 GAA, .934 SV%
2014-15: 15 games, 2.24 GAA, .906 SV%
He played on some very good Kings teams.
Schneider was 27 when he was traded and had played 98 career games. His numbers in his final 3 years in Vancouver (88 games) were impressive, and he returned the 9th overall pick. I'm not expecting Georgiev to return a top 10 pick, but a late 1st is certainly within reason. If there is a team that thinks he is a #1 goalie, then a 1st round pick is a small price to pay to be set in goal for the next 10+ years.
