Interesting things from the video.
Regarding defensive substitutions, we see the rule change that makes this a "Live Ball Foul." So, fundamentally, if we see more than 11 on the field, we hold until the ball is snapped, then toss a flag and let the down be completed, then report the foul.
As the Impractical Jokers would say, "Welllllllllllll…"
BY INTERPRETATION - as seen and spoken in the video - if the snap is imminent and no B player is attempting to leave the field, and Team A calls a time out, that's going to be a dead-ball substitution foul on B, and we don't charge Team A with a time out.
BY INTERPRETATION - as seen and spoken in the video - a departing player (in excess of 11) will have to be truly OB to NOT be charged with a live-ball substitution foul. No more "if his next step would take him off the field, he's OK." Gotta be off the field to not get stuck with a foul. My only question is: Does that mean at least one foot on the ground OB? That would be MY interpretation, but I'm not the interpreter.
No revelation here, but confirmation that fouls for infractions of the jersey rules will be a 15 yard penalty after the opening kickoff, plus a timeout, and then a timeout at the beginning of each subsequent period (still wearing illegal jerseys). What I don't know is: When is the timeout to be charged in the subsequent periods? When the ball is declared ready for play for the first down? After the first down? No clarification on that.
A player can wear another jersey over his 'base' jersey. He is supposed to report his number change. If he doesn't, it is a UNS. But how will we always know? We don't know these guys (even at high school). Billy Bob wears 55 normally, but they put 88 on him, send him in, and he doesn't report. I doubt I'd recognize Billy Bob wearing another jersey.
Well, probably another rule change that really just won't be a problem.
When I was umpiring minor league baseball, we had to keep an eye on the players during warm-up, to be sure they weren't fraternizing with the crowd, etc. We called it "rat patrol." So, now the NCAA "rat patrol" is 90 minutes. 60 minutes was OK. We needed the 40 minutes or so to warm up, record kickers numbers, chat with the QBs, talk to the BBs and chain crew. 90 minutes - OK maybe actually 70 minutes - just because the coaches can't/won't control their players and themselves? Geez. I hope NCAA guys get a big pay raise.
Good video, though.
