RIP Fugu
The Sharks had one of the league's best defenses at the time (Boyle, Vlasic, Murray, Demers, then added Burns in 2013). It's no coincidence that Niemi's numbers tanked once he left.
Your downplaying Niemi
Early on with Sharks his D was young kids (Braun , Demers , Vlasic) and aging vets like Huskins , Doulgas Murray , Boyle and a fading Nicklas Wallin
He put up a .920 sv pct with that D and went to WCF
And in Niemi's best year your overvaluing his D
Dan Boyle (Aging top pairing defender at 37)
Marc-Edwouard Vlasic (Very good #2 at that point)
Jason Demers (Struggled thru year with injuries and played)
Justin Braun (Up and down play that year)
Brent Burns (Who averaged barely 16 min a game)
Matt Irwin (No one is ever going to confuse Irwin with a good defender)
Douglas Murray (Clealry at end and worst player on Sharks D that year)
Brad Stuart (Declining at that point at age 34)
Behind that D he was a Vezina nominee
The reality is once Niemi's reflexes started to slow down (Natural with age) his style of play began to become an issue and he could no longer replicate his past performance
Also cant entirely put performance in Dallas on Niemi as the D (Especially team defense) was atrocious and was major reason Lehtonen was terrible as well
Ruff's team in Dallas was a poorly coached team defensively and it got worse in his final season
