Between Joey and Thurston and considering defence and attack, Joey was better. They both had all the skills in attack but Joey defended like a backrower, where as Thurston was a speedbump.
Full credit to Thurston though, he was always in the frame, always backing up and always chasing down breaks he influenced games as much as anyone I have ever seen thru pure desire and effort and that is how I will remember him but not GOAT.
