Stepan is wrong because he has no cards to play. He has no arbitration rights and we have more depth down the middle than we've had in a long time, including two top 6 centers in Richards and Brassard. We have a very tight salary cap situation.
From a negotiation perspective, all of this makes Stepan expendable. He hasn't produced consistently at an elite pace yet, he had one breakout half season and showed a high ceiling prior to that but didn't perform at a level that warrants anything besides a bridge contract.
He also said in his exit interview that he wants to stay and retire with the Rangers, claiming he cares about the team, but his demand of more pay could cripple at least part of the team because of the cap situation. It's not like Sather wants to sign him to 3 mil a year for the next 6 years, it's a bridge deal. He's still young.
If he wants to be here, and he thinks he can perform at a high level, let him prove it for 2 years. If not, let him get offer sheeted and take the first rounders.
