21 actually, because the defense didn’t do their job. If I use my timeouts, their offense gets to relax, because now they have 6. They can do whatever they want. And if they fumble a snap, or take a sack, it’s no longer devastating. Also tells your defense you have no confidence in them.
If you use the timeouts and they score, your offense is left basically hosed if there’s less than a full minute. They have to throw to the sidelines and get out. Keep the timeouts, you can still use the middle of the field.
It’s all variations in approach and situations. I wouldn’t say either is wrong, but I’ll say that if my team line up against yours, I’ll beat you on clock management.
