To preface, FL has mandatory water breaks every.single week, every.single.quarter....including the finals game.
In as far as halftime, I'm not seeing it being reduced and the 3min warm-up would seem to be an invention from the Legal department.
With game times, they seem to be different based on the brand of ball they're playing.
For FL, since late 90s-early 2000, it's at least 50% passes and only 30-35% completions; ergo, +65-70% plays with clock stoppages than before.
Pair that with every RB gets near sidelines and he's going out. (strange, never saw Payton or Sanders or Dorsett or others run OOB, ever).
Add to that all the new HS popping up every year and the dilution of talent, you mostly see point differentials of 25 or more, OR total scores upwards of 60+points.
Yes, 2.5hr or more is the norm, not the exception.
To me with my small mind:
*1/10: no stops.
*OOB or inc pass: set the ball and wind it.
