I think it definitely tarnishes his rep. He has 3 other future HOF'ers on his team, what else does Lebron need?
Lebron has chosen1 tattooed on his back, not chosen 5.
He's already lost two Finals campaigns, 1 more loss with only 1 ring will not look the best.
In saying that, what he's achieved individually is amazing and will have him up there still. He does have plenty of time to get to say 5 or 6 also. But he'd want to not waste the opportunities especially coming out of the weak arse East.
