Mick Cedar was greatly improved on the defensive end last year, yes, but he went from being "very poor" to "average". And being one of the Crocs best defenders -- on the worst defensive team in the league, no less, isn't much of a distinction. Too slow laterally to keep up with guards, too small to defend wings.
As for Chris, 31% is not a good number from deep. And the Crocs were godwaful at shooting the ball last year, so fourth on the team is nothing to crow about. But the problem with those numbers that none of them are true. Chris actually shot 27.6% (Mick was a touch worse at 27.3%) from deep last year, which is about as bad as you can get, especially remarkable because most people who are that bad from range normally don't attempt shots at all. His form is flawed and there is too much power coming from the wrists/hands/arms once they are above the head in the shooting motion, like a rugby union line out throw-in or a netball shot.
