Yes, weights, sleep pods, massage facilities, float tanks....I don't think any of it will translate directly to wins on a football field.
The Sabres were given one of the best "hang out rooms" in the NHL several years ago and the team only got softer. Correlation does not imply causation but the new locker room/lounge/snack area/hang out room didn't improve the product on the ice at all.
This stuff may help in luring free agents to Buffalo though, on both teams. So there's that.
