I don't think there's anything wrong with being intense as a coach; the only thing about being too intense (a la Donovan or Laimbeer) is the same trouble with being too "nice" as a coach, or too much a "player's" coach (a la Westhead or Karleen Thompson)... and that problem is that both being too intense or too nice only works as long as you're winning.
Winning cures everything. Staley could probably coach this team in this tournament just as effectively as Donovan, but they haven't seriously been threatened in this tournament. I agree with Staley being the coach for Team USA in the years to come, but I suppose I have my doubts as to how well the players would have responded to her direction following the upsets last year. My impression is that she's still a little too recently removed from being a player to be as effective as the Ultimate Authority as Donovan is right now. My sense is that once she's established a little more separation from the current players, particularly the ones she helped shaped the league with, that she'll be a more effective coach in the long run.
