Our bench should be pretty good provided Faves and Gobert are helthy as one of them seem to be in the game at all times. Then u have Mack, Burks, and Lyles who will all provide scoring, and Ingles and Neto to provide some shooting along with Lyles. I have not one problem with the Jazz rolling with this second unit, maybe the Jazz replace Ingles with a better shooter, but I don't see the Jazz doing that much better with someone else in his place.
I think this lineup is a great energizer for the starting unit. I don't see a very big drop off, in fact, I think they can keep things rolling out playing the other teams bench.
