Don't worry. Next season is as much a contract year for Rivers as it would've been without the extension. My sources tell me that at least once or twice in the history of basketball a coach has been fired with time left on his contract.
The excuses are now gone. It's put up or shut up time.
For those vocal opponents of Rivers, just sit back, relax and wait to see if he has any tricks left up his sleeve. You sat through this much of the show already.

Showing that his reputation on the court is anything but an act, Noah was clearly the most intense player we’ve evaluated in the way he approached the workout. He attacked the hoop ferociously on every opportunity, punishing the rim with powerful one-handed slams accompanied by loud, primal grunts (much like a tennis player…). He showed big and incredibly soft hands catching and controlling anything and everything thrown his way, particularly in the two on two drills where Corey Brewer tossed a few difficult passes right around his knees. His length is particularly impressive in the way he finishes around the hoop with jump-hooks, giving him the opportunity to finish plays above the rim in almost every way imaginable, and with either hand. We’re more certain than ever now that teams will be making a grave mistake if they decide to pass on him outside of the top few picks in the draft.
