Since when? For the past two year we've continually heard how the Cavs have a losing record whenever Bron doesn't play. Any time the Cavs would struggle in the post season we'd hear people saying Kyrie or Love needed to step up because "Lebron can't do it all by himself". The narrative is that when the team is doing well it's because Lebron singlehandedly carried them to a victory, but when they lose it's because Lebron doesn't have enough help and his teammates didn't show up to play.
Before Lebron went back to Cleveland Kyrie was looked at as a guy that could be a franchise cornerstone. He was seen as a ridiculously talented player that was hampered by an incompetent front office, now you got people openly mocking him and saying he wont be shyt without Lebron if he leaves.
Kevin Love was seen as a legit all star caliber players and even a few (mostly white) people were calling him a top 10 player. Now he's a guy that other teams aren't even willing to take as part of a multi team deal.
Since the team was formed Kyrie and Love have regularly been rumored as parts of trades whenever the team struggles. Who wants to play with that sword dangling over their head all the fukking time?
Playing with Lebron gets you more success, but it also seemingly lowers the amount of respect players get.
You're seriously overstating how much respect Love and Kyrie had before LeBron came back.
