Yea, I would consider Tara, O'Reilly and Petro elite talent. Saying STL won with no elite talent is being bit dishonest in my opinion.
Binnington was/is/became borderline elite talent.
You can be elite and not be a HOF talent like the next group of guys you mentioned. I'd consider Hedman and Josi to be borderline at this point.
Let's be honest, STL was stacked. Parayko, Steen and Schwartz ( one of the twoway wingers in the game in my opinion ) filled out that team pretty nicely.
If one was to say, you don't need HOF talent to win the cup, I can agree. But can you win without Elite talent? I disagree, during this day and age. Vegas got close as you can get, but still had elite talent in MAF in net. Who will be HOF.
You need elite talent all I am saying.
