The entire narrative is "how to beat Lebron" all the time, not how to beat the Cavs.
For that reason alone, and the diminished endorsement opportunities from being a Lebronette, are reason enough to consider other opportunities for a top level player.
And for a guy several years younger than James, one might wonder how long he can keep it up. He is already taking minutes at PF, and likely will take more as time goes by, which is Love's position.
Things to think about if I were Love.
Might take one more year in Cle, but not sure I'd sign up long term.
