Th LeBron never has help narrative is getting old. He played with Ray Allen (HOFer), D-Wade (100% chance of being a HOFer according to Basketball Reference), and Chris Bosh (99.5% to make the HOF) in MIA. With CLE, Love has a 676.% to make the HOF and Kyrie 36.4% so far.
When the season started, the Cavs had a former MVP in D-Rose, Wade, IT (2nd team All NBA last year), and Corver (an all star a few years ago). It's not like the Cavs had nobody. Not sure why they made all the trades they did to get rid of players with more experience or had done something in the playoffs. LeBron contributed to the roster as much as anyone else.
