I am not saying he should shorten C5, but it finally occurred to me why he may want to.
Self is doing some pretty clever substituting to get these double doubles.
Maybe he doubts he can keep this up.
Maybe Self figures the top opposing coaches are going to figure out his substitution pattern and figure out how to counter substitute.
Maybe the magician knows the vulnerability of the C5 trick best.
Whatever, it's been a damned good trick so far.
Double doubles every game.
