Actually I don't even understand why the writer chose Monta Ellis as his example. He's peaked high and bottomed really low during his entire career so his reemergence wasn't really a surprising one. Ellis when he had team to his own constantly flirted with PER 18-19, and he's now duplicating that 19 season again within the system where he's allowed to use possession to his liking unlike with Jennings where he wanted to dictate middle of the floor while drawing little attention as a perimeter threat due to his poor outside shooting.
Now if Gay is to succeed, he probably needs to go Jordan Crawford and make an unseen transition to a different player at different role. But I agree with benji that it's not likely. Jordan Crawford at least shown he's a willing passer at times (I called this, he's going to start this season along with Sullinger and they'd excel) and his facilitating skills are far better than anyone on Celtics roster and JC is fully taking advantage of it. Having Bradley helps too because he's a dirty work player that'd do anything that JC wouldn't want to do. Gay is just in a different spot. How could he make a transition to a powerforward successfully when he now posts up against much bigger players and he doesn't have that kind of post game anyway. He's going to still turn to his face up game and take contested jumpers which wouldn't change jack. And try banning stats this time, Cousins will give you that death stare. It's still gotta be Cousins's team, Gay better not mess it up.
