Granted totally hypothetical but wouldn't this be for the best? Bishop Gorman has won the Nevada state championship in '07, '09, '10, '11, '12, '13, '14, '15 & '16.They win the state championship game by scores of 84-8. Gorman has a monopoly over the talent in Las Vegas. If they move to the Trinity League they will at least have competition.
Every team in the Trinity League including Gorman has more than enough money to travel. Once every two years a CA Trinity League school travels to LV. Gorman plays LV teams first 4 games then travels to CA 3 out of 6 League games. Three travel games is more than normal for the Gaels.
I know there are cases where schools in one state play league games in another. For example, Needles High School in California plays in a Nevada League.
Would be interesting.
