That "impressive array of talent" in Cleveland consisted of a chronically injured defensive liability in Kevin Love (who left his best years in Minnesota, was gone from the playoffs entirely last year and barely saw the floor in the Finals this year) and injury-probe Kyrie Irving (who was gone from the Finals last year). Oh, J.R. Smith is there, too, I guess. After Love and Irving were gone in last year's finals, Delly logged significant minutes and the second-leading scorer was Timofey-freakin'-Mozgov.
Wade was about to enter the back 9 of his career, battling injury problems, and Bosh was a really good player, never a great one. LeBron made those teams title contenders, and they were also-rans before and after him.
During LeBron's first seven years in Cleveland, the best player he had on his team was Zydrunas Ilgauskas, and he dragged an absolutely putrid team to the Finals.
GS won the title last year and were a few minutes away from joining the discussion of all-time greatest teams this year. They have the two-time reigning MVP (current scoring champ), two All-Defensive first teamers, and four all-stars in their starting five, and that's not even counting Durant. They were already the championship favorites for next season!
Let's not pretend that having a few other good players and giving yourself a chance at a ring is in any way comparable to what GS has and what Durant did. Unless you think that the 2009 Heat plus Chris Bosh and Mike Miller (or the 2016 Cavs minus LeBron) are on the same level as Golden State, in which case I don't know what to say.
