After '66 he was adequate in forming the Beatles sound? As what: song writer, guitarist, musical innovator. I just don't get it, what did he lack that makes him only adequate? His talent is just as great as McCartney and Lennon, heck John even said that without each other none would have made it, "None of us would've made it alone, because Paul wasn't quite strong enough, I didn't have enough girl-appeal, George was too quiet, and Ringo was the drummer. But we thought that everyone would be able to dig at least one of us, and that's how it turned out." Dana ; )
