The way it's worded the Rags are willing to go above 10.5M but "there are limits" as if Shesterkin wants way more than 10.5M. Dude has won nothing outside of a single Vezina and plays in a popular market, that'd reset the goalie value big time.
Here's the thing--contracts should be paying for future performance, not past accomplishments. "Reward" contracts are usually disastrous (see: Seabrook, Brent). He is arguably the best goalie in the league, I certainly would put him an entire level above his contemporaries (he doesn't get anywhere near the help Swayman does). DGAF if he hasn't won anything, he's already proven his value to the team.
He knows he's got them by the balls. And they know it too. I don't blame him one bit for negotiating tough, I certainly would if I were in his place. Frankly I think his predecessor left money on the table and the Rangers did f*** all with it.
Trouba said the quiet part out loud, that this is the last ride before major changes start happening. Shestyorkin is basically telling them "Hey, you want me to stick around? You'd better pay me."
