Small nitpick but won't that be Smart's job to start the 1st and 3rd Quarters, guarding the opposing teams best scorer? and if Jaylen comes off the bench, won't that be the same time the opposing teams best scorer gets a rest?
In crunch time (late/tight) I'd expect the small ball team to be Kyrie, Gordon, Tatum, MaMo, Al (w/Smart coming in for Kyrie for a defensive situation).
Actually, Jaylen's defensive assignment would be to shut down the opposing teams best bench scorer, something he could do in his sleep. A bench role for Jaylen could be quite beneficial to him if he embraces it. He'll play with Hayward, who is getting healthier/better and will distribute the ball more to Jaylen. He'll get more minutes with Baynes, who will set wipe out screens for Jaylen. He had good chemistry with Rozier last spring. Plus the pressure might be dialed down as they start winning. His efficiency numbers should skyrocket after such a rough start.
