High school officiating is always inconsistent, and often even more so in postseason. Officials come from different sections to do games and sometimes aren't used to the pace and style of play; and players and coaches aren't used to these new officials.
I do know this: Often a discrepancy in free-throw attempts reflects more on the way the two teams are playing than it does on the officials. A team that goes to the basket more, has more quickness, creates contact without charging, will wind up with more free throws regardless of who's holding the whistle.
And of course there are times when the officiating is one-sided, but I can't take the total number of free-throw attempts as a perfect indicator of the quality of officiating.
In the end, of course, you have to be 10 points better, or maybe more, to overcome the random walk of referees' calls. And in postseason at this point, of course, few teams are 10 points better so the officials can become more crucial.
Every team can come up with reasons why it won or lost, but when the horn sounds, the scoreboard doesn't lie.
