I've heard all the reports, and hope like heck they're all true and he's back to 100%. I'll believe it after I see it, though.

Yes, if he is honest to goodness back to being Nick Chubb, then it doesn't matter who the QB is (or rather it's the guy who can hand him the ball the best). If on the other hand, he's serviceable but not quite superman (I think more likely, at least for the first couple games), then my guess is Lambert starts with Eason seeing time and ultimately getting the start a few games down the road.
