Because of the whole LeBron problem that eventually awaits, I don't know if Fred's game-to-game adjustments will even matter. The bigger issue is that this team just straight up doesn't have the talent to be a title contender. They have a couple guys (Rose, Butler, Gasol) that can keep them competitive, but their role players are going to get totally exposed in a playoff series against the top teams in the East. You can't beat the Cavs or the Raptors in a seven-game series having to play E-Twaun or Justin Holiday significant minutes, and McDermott and Mirotic are too inconsistent to count on at this point. I like how Doug's playing right now, but again: in a series, teams will make adjustments, and the adjustment to him is easy. Just stay in his pocket.
We have at least one more year of basketball purgatory before we can really expect Fred to find his footing. As constructed, this roster just isn't going to do what he wants it to do after a certain point. That's essentially what kept happening to the Bulls in the Rose-less years and even at the end last year with Thibs; they reached their limit, and then they got put away because they were either not good enough or not rested enough. After this season, Pau's probably going to be gone, Noah's definitely going to be gone, Rose has a good shot to be gone in a year or two, and whether you want to or not, this thing's going to have to start from scratch. There's no window this season.
