Considering that Exum is virtually unplayable in the second unit, that he has very good lob chemistry with Gobert, and that Joe is playing too many minutes, I propose the following:
Sub Joe at the 6:00 minute mark in the first quarter for Exum, who then plays for about the next three, which ensures that someone remains in the lineup to feed Gobert while he is in, then sub out Exum for Mudiay. Then sub Exum in either for Mudiay, or when Gobert checks back in for about another three minutes. Then bench Exum at the 6:00 minute mark in the 2nd quarter for Joe. This means he basically plays 12 minutes a game and that they come from Joe. This ensures Dante’s skill set isn’t as duplicitous, his weaknesses don’t bump into everyone else’s, and he’s not too relied upon either, setting him up for success if such a thing is to occur.
That’s the only scenario that makes sense to me. I would like to see Exum get minutes and/or shipped out just like everyone else since keeping him benched is really just embarrassing for everyone, at best.
