I firmly believe its Al Jefferson. The games where Jefferson doesn't play the offense runs so much more smoothly. I also think that Hornacek would not let the offense get so stagnate. He knows the flex offense better than anyone. I don't think Ty Corbin is a coaching genius but I also think I will wait to see how the offense is with Jefferson gone. So I guess I am saying: Ty Corbin>Al Jefferson That dude just needs to go.
