Tim Thomas is a weird case. I don't really think you can compare him to anybody, because his peak was debatably the best of any goalie ever.
Thomas did have some of the best 4-5 years of any goalie ever, at least as far as personal play goes. I think he'll miss out though, due to longevity.
If you put Kipper in, you have to put Vokoun in.
Vokoun is another one. He doesn't have the Vezina that Kiprusoff did, never went to a SCF either, but I think he was a better goaltender than Kipper. He was good in Nashville, he was really good in Florida, they were just a really bad team while he was there. I don't think he was ever on a team with a legitimate chance of contending. Maybe the 2013 Pens, where he was originally supposed to be the backup, but took over for Fleury in the playoffs, after he was really awful for the first few games. And Vokoun was awesome during that run. I felt bad for him the most on that team, after they were swept by Boston in the ECF. He played awesome, but his team barely average more than a goal per game in that series. He was easily the most underrated of that era. His lack of playoff appearances/big game appearances were the product of playing for some BAD teams. Not even just mediocre teams, but BAD teams, outside of his last couple of years in Nashville. I'm glad he had that playoff run in 2013, since he was more than deserving of playing some big games like that. It put a cap on a career, where he massively underachieved, due to playing for mostly awful teams.
I only personally mentioned Ryan Miller, as he has a Vezina, much like Kipper did. And he might soon be the most winning American born goalie of all time, but Quick will pass him and smash that one, as he has much more career left in him. I do think Kipper's best years were better than Miller's best. I always considered Miller just an above average/solid goalie. Never really elite, outside of that one season. Vokoun was much more consistent than Miller was.
