The Warriors and Rockets have a few similarities: skill at shooting three-pointers, guards who dominated the MVP talk, a long stretch of not being particularly good.Here's one big thing the Western Conference Final opponents have in common: coaches who have followed the same path.Kevin McHale and Steve Kerr are former players who got back into the game as general managers, worked as television analysts and eventually found themselves back on the sideline coaching.Last spring, when Kerr was thinking about his options, he was doing some Rockets playoff games for TNT.After his stellar 13-year playing career in Boston, where he won three championships, McHale was a general manager in Minnesota, briefly the coach there and then a TNT broadcaster before he became coach of the Rockets in 2011.McHale, 57, gave one of the most comprehensive explanations as to why a man in his midlife years, with all the money he needs, would go back to an NBA bench for an 82-game grind.
