Gotta be more to it, although I have no idea what it could be. Driver's are like any other sports athletes. Only the best of the best ever walk away on top. Almost always end up being shown the door unceremoniously.
Any chance they let Button drive for a year or two until someone like Max becomes available? JB ain't the best, but he treats his equipment well and won't rock the boat.
Better question....is Merc brass happy or pissed?!
Get that rumor mill going!
