I think Phil Jackson will walk away from the NBA at the end of this season. At least temporarily. He looks like a guy who needs a break from the grind of the NBA lifestyle. All the travel, media and other daily irritations. I think he's a guy who wants some time to himself.
Give him a year or two away from the NBA ... and then see whether he has regained that thirst to coach.
Also, it's hard to imagine Pat Riley putting his gigantic ego aside and hiring Phil Jackson to turn Riley's Heat team, the team he built, into winners.
