Why is it sad? The guy can still coach. It was KOC and Greggy Boy that forced his hand. He wanted discipline and respect. If a guy is quitting on his teammates and not running plays, something has to give. The FO either sides with the coach or the player. Orlando sided with Dwight over SVG. Utah sided with Deron over Jerry. And in both cases, the player was dealt anyway.
WE don't know why he's there. Could be in a coaching capacity. Phil Johnson was a former COY and then became Jerry's assistant. Or he could be there under the invite of Pops or Scotty Layden to assist with player evaluations. If the guy loves basketball/coaching and misses being around the game, then by all means he should pursue whatever job he feels suits him. In fact, maybe he wants a lesser role due to his age and "consultant" is his way to be involved, but not have to be on the road for 41 games every year.
