In terms of Love being back with the Cavs. Because of his playmaking ability, getting guys involved, and his under-utilized post up skills, I think it would make sense to utilize him with Kyrie as much as possible. I think it could work out quite well on the offensive end of things while Lebron's minutes can be distributed to play more minutes with the second unit because the playoffs proved he can take a team of scrubs to the finals.
Have Kyrie and Love play heavier minutes together along with defensive minded players (Shump, Delly, and Mozgov) while you distribute Bron's minutes to play more with spot up shooters (Mo Will, JR) as well as Varajao and TT.
Obviously I am not saying LeBron to come off the bench (plz don't think that), I am just saying the minutes can be distributed more efficiently to maximize the effectiveness of the entire squad.
