Stepan-Brassard-Miller is a recipe for disaster, and something the organization would never in a million years do. If any one of those players fails at their respective positions (Stepan at 1C, Brass 2C, Miller 3C), we literally have no back up plan. Not to mention that Stepan is the only defensively competent center in your Top-9, and none of them can win draws. You can't just throw your 4th line out there for every defensive zone draw.
I think it's a foregone conclusion that Richards gets bought out, the risk with that contract is simply too great. But does anyone really expect the Rangers to buy out Richards and NOT replace him? Stepan could have a bounceback season and play 1C hockey, but Brassard is way too inconsistent and weak defensively to handle 2C duties long-term. Next season for Miller should be about solidifying his spot in the lineup. To put him in a sink-or-swim situation at 3C is moronic.
I don't know what the solution is to be quite honest, but management won't sit and do nothing. Either by trade or free agency, Richards will be backfilled. To expect anything different is willful ignorance.
