Bergevin should definitely offer him a contract extension for at least 7 years.
Nick Suzuki's contract with the New Jersey Devils is comparable to Hischier's 7-year, $7.15M a year. Two solid guys who can easily score 50 points per year. In the long run, it's definitely what the Habs forward wants, especially if he explodes this year. Suzuki is the future of the franchise, and we should prioritise him before we favour another Habs player.
