I hear you, bro... but think about this: Hood and Hill already have good chemistry together as a backcourt. So .. I'm not sure why we wouldn't want to exploit that.
Hill and Hood were a net +8 all season and postseason last year when playing together. And if you look at the various lineups, this trend stood across pretty much all other player combinations.
For example:
General net rating while playing together:
Jazz Points Per Possession (PPP) = 1.14
Jazz Opponents' PPP = 1.05
Jazz Net Rating = +9 points per 100 possessions
While playing with Hayward and Gobert:
Jazz Points Per Possession (PPP) = 1.15
Jazz Opponents' PPP = 1.02
Jazz Net Rating = +13 points per 100 possessions
While playing without Hayward and Gobert:
Jazz Points Per Possession (PPP) = 1.14
Jazz Opponents' PPP = 1.03
Jazz Net Rating = +11 points per 100 possessions
With Gobert, no Hayward:
Jazz Points Per Possession (PPP) = 1.08
Jazz Opponents' PPP = 1.05
Jazz Net Rating = +3 points per 100 possessions
With Hayward, no Gobert:
Jazz Points Per Possession (PPP) = 1.205
Jazz Opponents' PPP = 1.213
Jazz Net Rating = -8 points per 100 possessions
So the only combinations that were negative was when Hood and Hill were partnered with Hayward but no Gobert. Interestingly, though, when Hayward is not required to play, Hill and Hood are positive again.
Jazz Points Per Possession (PPP) = 1.16
Jazz Opponents' PPP = 1.13
Jazz Net Rating = +3 points per 100 possessions
Overall, Hill and Hood are really good when they are playing together. The Cavs should use them together during most of their respective minutes. I am good giving JR time while Love is hurt, but if he does not sustain the level of play from the last ~7 games, you have to bench him and stick with Hood.
