That value is a gross underpayment. You need to step away from the homerism of Miller and realize the situation with Tarensenko because hes still on his ELC and is easily controllable and affordable. Miller is a rental and 33 years old and going to be wanting Lundqvist money. Tarensenko is a big part of the St. Louis offense while Miller is an uncertainty.
In short Tarensenko is untouchable unless we grossly overpay.
Everyone needs to realize we won't get much for Miller, in hindsight he will fetch a goalie and a pick. Don't expect a young NHL proven forward for a rental goalie unless Miller is willing to do a sign and trade and I highly doubt he will because he will want to see what Anaheim does in the offseason when they let Hiller go.
We will probably have to package Miller with a young defensive prospect for a high quality young NHL top 6 forward. Why? because that's where the market is for goalies and anyone else who thinks different is just kidding themselves.
There is a difference between between gauging "fair value" and gauging what it would take to get a deal done when a team views a guy as "untouchable".
You said previously it would take Miller and a Sabres 1st to get Tarasenko.
I think that is a huge overpayment for Tarasenko given where the Sabres will likely pick in the 2014 and 2015 drafts.
And any deal centering around Miller and Tarasenko isn't a good one. If St Louis needed D (which they don't), then a deal centering around Tarasenko and Zadorov or Ristolainen would make more sense.
The bottom line is that I agree that the Sabres aren't going to get Tarasenko in a deal where Miller goes to St Louis. But, I don't think Tarasenko trade value is where you think it is if you think the Sabres need to give up Miller and a top 5 pick to get at a fair market price.
