Technically yes, but it was Stan's "speculation" that came up with those inflated salary numbers. He was the one who broke the rules of good business practice.
Obviously every dollar matters in the cap era, but let's take a look at some of the highest contracts in the NHL...
Anze Kopitar: 10mil
Are Kane and Toews worth roughly the same as Kopitar? Yes
Jamie Benn: 9.5
Are Kane and Toews worth a million more than Benn? No, they should be about the same.
Ovechkin: 9.5
Are Kane and Toews worth a million more than Ovechkin? No, they should be about the same.
Malkin: 9.5
Are Kane and Toews worth a million more than Malkin? IMO yes, they're more complete players with more durability, many would argue no tho.
Crosby: 8.7
Are Kane and Toews worth two million more than Crosby? Hell no, this is a massive sweetheart deal from a superstitious kid.
Perry: 8.5
Are Kane and Toews worth 2 million more than Perry? Yes.
Stamkos: 8.5
Are Kane and Toews worth 2 million more than Stamkos? Yes.
Giroux: 8.2
Are Kane and Toews worth 2 million more than Giroux? Yes.
Voracek: 8.2
Are Kane and Toews worth 2 million more than Voracek? Yes.
Getzlaf: 8.2
Are Kane and Toews worth 2 million more than Getzlaf? Yes.
Kessel: 8.0
Are Kane and Toews worth 2 million more than Kessel? Yes.
Nash: 7.8
Are Kane and Toews worth 3 million more than Nash? Yes.
Tarasenko, Spezza, Oreilly, Parise: 7.5
Etc
With the exception of Crosby, Ovechkin and Benn, I'd argue Toews and Kane are fairly paid relative to their big-contract peers.
