This is exactly the kind of thing that happens in the NFL when a WCO-style timing offense is put into place. The gestation period for a QB to truly arrive in such a system is about three years, provided the receiving corps is solid enough to run precise routes and gain an affinity with the pivot in question.
Some QBs never can make the transition into that kind of timing system. Vinny Testaverde is a perfect example of this.
Chang's run-and-shoot/spread/Hawaaiian Punch offense had many of those timing elements. However, it is built upon the QB being mobile enough (whether finding time in the pocket or rolling out) to create on the fly once the play begins to break down. He has had years in that system to develop the improvisational skills to make big plays on the run.
You have to be decisive in running any kind of timing offense re ball distribution. One has to have the arm strength to put the ball into seams in the 10-20 yard range to stretch the defence and help establish the run game. It means a flatter plane. Chang seems to have a lot more gas on his ball that Maas does for that task, going by what I saw last night.
Chang's footwork is very good, IMO. He should be able to adapt to Taaffe's system because he's had timing issues to work with under June Jones in Hawaii. His learning curve is certainly not as steep as Jason's in that regard.
