I respectfully agree with your disagreements on every point. this discussion was played out at the beginning of the season, Knicks have played fine just as it is, and JR winning two games with last-second shots shows how it's working. It's all about the defense stepping up, not about JR starting. Harden/Terry, yep. a strong 6th man off the bench is what it's all about.
not only that, but JR comes in VERY quickly, so it's hardly like he's benched. if anything, he's hanging with the coach on the pine, and knows his role is to be the spark plug who ignites the offense, or take over the 2nd unit, and eventually finish the game. it's all about the minutes and the contributions he's currently making, why change a thing?
