I think he'll play 2 more...unless he gets a ring this year.
Niners have to be ready for him to leave. Getting Tank ready, moving Dorsey to DE, or drafting another DE or 2 this year...they need to be ready for the Cowboy to retire.
Personally, I think his play fell off a bit this year, but he's still pretty damn good.
