I reckon his more then fit enough, its just the doctor percutions that will proberly hold him back, let alone there still may things that mri's havnt shown ect.
Who knows he might just loose his nerve trailing another car in fear of something happening.
My thoughts really but thats all they are, id be wrapped to see Massa back, but would rather he came back when he was ready rather then premature.
So all in all, im on the fence wheres the dont know option?
