AB, like others have said, is a specialist and he has unique quirks about his game. He has the talent and work ethic to carve his way nicely into a rotation. Whether that's off-the-bench as a disruptor or as a starter, it will depend on the personnel. But simply put, he's a role player and you add role players to a system, not the other way around (which would be building your system around role players).
FWIW, i think AB would flourish more with a ball-dominant, playmaking wing (like Harden) rather than a ball-dominant, playmaking PG (like Rondo).
