Outside of the general narrative he's most known for (a boundless talent who rarely plays up to his potential), Jeff Green's been a disappointing player this season.
Stevens has nudged him to evolve as a playmaking threat instead of letting him stay comfortable as the one-dimensional scorer he's been, but there's been very little development there. Green runs the occasional pick-and-roll, but it's extremely rare anything substantial comes from it. He doesn't make the defense work.
From here on out, maybe Stevens should be more forceful and demand Green to look for passing lanes instead of his own shot. The Celtics won't be a very good team if their leading scorer barely shoots 40 percent from the floor with a below-average PER.
Even if Boston has plans to shop Green this summer, it's best to boost his trade value, and that means turning him into the best player he can possibly be.
Also, how about showing more effort as a rebounder and more awareness as a defender away from the ball? Stevens should unleash Green on the boards and tell him to be more aggressive in an area he shouldn't be so horrible in. (Green is 11th on the team in total rebound rate, per Basketball-Reference.)
And as a defender there's really no excuse for most of his mental lapses. The tendency to focus on the ball and get beat back door needs to stop. It's correctable.
Stevens has the authority to bench Green, one of his best players, if the all-around play doesn't improve. This is obviously a last/worst-case scenario, but anything to get his attention should be considered. This isn't about turning him into an All-Star. It's about making him competent.
