Most likely.Yeah Neji inspired Lee the most, I think Lee has lost some of his drive.
By "sake", I thought you meant the alcohol. That would've actually made sense. Drunken Fist Lee. LOLTrue but you never know lee could be like I'll become stronger for your sake put of nowhere and BOOM OP lee
Obito and Kakashi were never rivals. It has been Guy and Kakashi from the start...kakashi had a rival during ghis chuunin days ...Obito Uchiha ...
Obito's death made him realise the true meaning of ninja ..which gave him inner strength ...
He eventually got into Guy's trap and became his rival ...
so I don't think we can say this for sure that 'lee will never surpass guy or vice versa'
In order for a person to be a rival, their overall power must be around the same level. Current Naruto is way too high to be anyone's rival.Naruto will be his new rival. That's a pretty high goal to shoot for.
