Hell no. Van Gundy commanded no respect. He would have had a ton of egos, playing for a Ron Jeremy look-alike with no rings, and nothing to his name.
THey needed a superstar to coach the superstars. This team would have been at each others throats halfway through the year after a few losses. Complaing about Van Gundy. It would have been players bickering in the lockerroom about Van Gundy, and excuses, excuses.
Riley creates an us against them mentality. Its the Heat and their families vs. the world, the media, the refs, the opposition. Everyone is out to get them and they need to stick together. He did a great job.
Hell Shaq was already complaining about Van Gundy last year for not calling any plays to get him the ball late in the game. Riley is a master of motivation and getting those egos to play together. They are supposively a very tight group, and you can tell from their celebration that they were.
