I don't know if Sizzle is biased, but he is right. hornsr1 is biased, and also wrong.
In many, many series in 5A this year, the loser of the first game has gone on to win a best of 3. If the weaker team can get lucky and win a best of 3, as hornsr1 suggests, then of course it is more likely that the weaker team can win a single game.
I really don't know if PW is really better than Flower Mound or Jesuit. I do know this--the PW coach doesn't think so--he was unwilling to play either team in a best of 3. He thought he could win with his best pitcher on the mound--he didn't think he would win if forced to go deeper into the roster against those teams.
