Regardless, he isn't worth 6.5m.
I have typed that 3 times now and I can't type it any slower.
About a decade ago, when the Sabres were right at the beginning of the tank and rebuild, the Sabres reportedly offered Shane Doan a contract worth $7.5M per season. That offer was considered a massive overpayment. Doan stayed in Arizona regardless.
Looking back now, having Doan as the captain when bringing in Eichel, Reinhart, and the youth drafted during the Sabres tank year would've saved the Sabres about 6 years of heartache. The Sabres failures since 2015 had nothing to do with skills. It was all mental and maturity. In that regard, Shane Doan would've been worth $10M per season.
The Sabres have the best young blueline in hockey. Dahlin, Samuelsson, and Jokiharju are all 22. Power is 19. Buffalo is actively looking for a veteran to add onto the blue line, and it's not for skill. Buffalo is looking for a veteran to help those kids navigate the NHL game, on and off the ice.
In that regard, $6.5M is a bargain.
