After watching the last 3 runs,
1st down, Carr under C in a 2TE set with Waller left, and Moreau right. Run call left G/T side with no pulling TE leading the way, and the play is stuffed easily for a loss.
2nd down, Carr in shotgun with Jacobs to his right, it's a 1TE, 3WR set, with Waller on the right. Renfro goes in motion from right to left. Run call left G/T side with no pulling TE leading the way, and Jacobs bounces it outside after a nice block by Miller over Bosa for 7 yards.
3rd down, Carr in shotgun with Jacobs to his right, it's a 1TE, 3 WR set, with Waller on the right. Renfro goes in motion from right to left, (hmmm, didn't we see this last down)?
TO is called by Staley, and he changes his personnel plus formation
3rd down, Carr under C in a 1TE, 3WR bunched up set with Jacobs lined up about 5 yards back. Carr motions Zay Jones right to left, and once the ball is snapped, Moreau starts to pull from right to left as a lead blocker. Moreau takes out Bosa, while the Charger's LB White takes himself out of the play for no reason, and their safety, Adderley, is off doing his own thing in no man's land. Jacobs hits the hole behind the excellent block by Moreau on Bosa. Both Charger linemen Jones and Joseph have a shot to stop him at the 35, but Jacobs has the power and momentum to slip by them, and blast by Samuel to add another 6 yards to the run, downed at the 29.
Here's the obvious. Raiders were lined up with the exact same formation, with the same personnel and pre snap motion, on that 3rd down prior to the snap as they were on that 2nd down run play, but before the TO was called. Everything changed after the TO was taken, and they came back lined up with different personnel, formation, pre snap motion, and a lead blocking TE pulling from right to left.
One can debate if that run before the TO being called would have been stopped or not, but the Raiders were in the exact same formation, had the same personnel, and same pre snap motion as the previous down, so it would appear to most that they were about to run the exact same play as before. I'm pretty sure the SD defenders knew this as well, since they were on the field the previous play. It's plainly obvious the TO call brought about a play call change, which cannot be debated. Yes, it was still a run call, but nothing like what was previously shown in that sequence of plays.
