Don't forget the 1st unit was out there for about 2:20 as well before the TV timeout near the end of the game. BB probably not wanting to risk them running out of gas (especially as Getz and Kesler would be used to wind the clock down).
That would be a good reason too. But I still thought the second one looked better than the first. Especially if BB insists on rolling Bork with them.
