I agree OP, although I always thought of Kelly the play caller as Jekyll and Hyde.....
It can be beautiful, or it can be predictable and head scratching.
I feel like his offensive play-calling is completely random. Like he blindly throws darts at a dart board to decide what he's going to do next play, next week, next year. No real identity after 7 years. Just like he can't establish who the starting QB is... throw a dart.
