Totally disagree. Goaltending is one position where I don't think there's much drop off. Heck even as recently as last season we were seeing most of the leagues best point getters (7/10) and goaltenders (Rinne, Brodeaur, Thomas won their Vezinas in 30's).
Look at the age of the current NHL starters. Outside of a handful of players there's a ton of HF certified old farts manning the crease as their teams #1. Price will be like 38 when the contract ends. Rinne is 36 and still playing strong, won the Vezina at 35. Luongo is 39. Anderson is 37. Howard is 35 in a couple of days. Lundqvist, Crawford, Quick, Dubnyk, Fleury. All these guys are hovering around their mid-30's and don't look close to being usurped. Unless a career jeopardizing injury happens I can't see Price not being a Starter even at the backend of his contract.
