“If the game is interrupted due to weather during the last three minutes of the second period, and the delay is at least 30 minutes, the opposing coaches can mutually agree to shorten halftime intermission, provided there is at least a one-minute intermission (not including the three-minute warm-up period).”
I'm all for this in general, but I think there needs to be some eventual tweaking of the warm up period.
Scenario: 2 minutes left in the 2nd quarter, a storm rolls in, lightning flashes, game halted. The weather delay lasts 45 minutes (just to pick something arbitrary).
After the storm clears, teams return to the field to finish the second quarter. This is the point in time where both teams need to warm up because they've been sitting in their locker rooms for the last most-of-an-hour.
The come back to the field, play two minutes of football, have a 1 minute intermission by mutual agreement -- AND STILL NEED THE 3 MINUTE WARM UP??? Ideally they just did that 3 minute warm up 3 minutes ago when the came back to the field after the delay...
If the weather related halftime shortening can be invoked like this, the mandatory warm up period should be moved to the time they return to the field to complete the second quarter, not still mandatory as part of "half time".
