i didnt get that either. not that i am a fan or so, but idk why you wouldnt line up in freeze mode and then call the timeout with a few seconds left.
1) they might jump offside on fake snap counts
2) if not, you can see first hand at how they line up against your formation and maybe see that a safety moves down, zone/man, etc.
maybe they didnt want to give the D a chance to gather themselves, but the 3rd & 2 call was (although fairly obvious) sniffed out quite well and idk why you wouldnt talk about the most important play of the game for another minute.
