Question : If you use Coaching Points to change the yardage gained, negate a penalty etc., can the other coach immediately spend their points to cancel what you just did?
Answer : Yes. This is sometimes done by coaches to “use up” their opponents Coaching Points. (ie, if you have 8 points available and they only have 3, you could spend 3 points to ignore a penalty against yourself hoping they would spend their 3 to put it back in place. That eliminates their opportunity late in the game to spend points when you still have 5 left. There can be a lot of strategy related to Coaching Points – do you spend niggling amounts for small improvements to your situation or save them in case the game is tight later?
I think its wise to hang onto 3 in case a big play gets negated, but next game I play I plan on using all but 3 for better clock management near the end of a half and see how that works out.
