Last year, playing for Montreal, Condon had a 903 save percentage. Montreal was a train wreck but part of that was getting sub 500 goaltending for the 2nd half of the season
last year playing behind that train wreck that was the Ottawa Senators, Anderson had a 916 save percentage and Hammond had a 914 percentage. Hammond had a difficult year, injured in camp, played spot duty, wasn't putting up great numbers, but got a good run towards the end of the year and with the extra work his play improved substantially and he salvaged the year with a 914 percentage in front of a pretty weak defensive team.
There's just no way Condon would have been handed the reins of this team unless the team had no other choice. Hammond earned that right and as I said, unfortunately injuries haven't let him build on his run from two years ago.
First off, we got Condon because both Hammond and Anderson were out, though I imagine we would have gone after a backup either way.
Nobody said Condon would be handed the reins, I said he never got a shot to compete for them. Once he was given a shot, he clearly showed to be playing at the higher level. You can debate whether that will last, but he's got the better pedigree, and he passes the eye test as a better technical goaltender. Hammond's best attribute though is that he doesn't give up on a play, so credit where it's due.
As for comparing Hammond and Condon's sv% last year, I think when you look at the numbers closely, you'll find that Condon likely faced a more difficult situation;
While they were in net, Ottawa allowed 30.14 SA/60 and 56.73 CA/60, while Mtl allowed 27.74 SA/60 and 52.97 CA/60, sounds like an easier night for Condon, but not so fast. Mtl allowed very similar SCA/60 as Ottawa, 20.56/60 for Ott, and 20.05/60 for Mtl, so right there, the average shot for Condon appears to have been higher quality as about 36% of Hammonds CA were also SCA, whlle close to 38% of Condon's CA were also SCA. It gets worse though, in terms of HDCA, Ottawa allowed 9.74/60 in front of Hammond last year, while Mtl allowed 9.82/60 in front of Condon. That means more high danger chances against with fewer total shots, which will not be beneficial to a goalies sv%.
All that, and I haven't even broken it down to the portion of the season where Mtl had all the injuries.
Point is, sv%, even if you break it down to just looking at ES, is still a very rough gauge of how a goalie is actually performing. I'm not saying Condon had a great year, or that Hammond's was terrible, but I am saying that Sv% doesn't really tell the story one way or another, and you trying to play up how terrible we were defensively only works if you believe that Mtl was playing fantastic D, which they clearly were not.
Of note, we actually played significantly better in front of Hammond compared to Anderson by all the above metrics, it seems like the team tightened up in front of Hammond knowing they had to help out. In Mtl, the opposite was true, Price benefited from much more favourable scoring chance numbers and High danger scoring chance rates than Condon.
At the end of the day though, what's really relevant is whether you think if Hammond was healthy right now, would he be playing ahead of Condon. If the answer is no, we aren't playing our 3rd string goalie. At some point this season (and imo, very early on), Condon quite clearly passed Hammond on the depth chart.
