20 - 25mins half time

Does anyone know what was going on at half time on Saturday? Why did it take up to 25mins for both teams to re-emerge?

It was a bit of shadow-boxing/tactical warfare between the two managers.
McGeeney tried to call Bradley's bluff when he sent out the Kildare subs but I think Bradley had the last laugh (if there was one to be had by coming out second for the second half?).
It was funny when one of the linesmen had to go in and tell the two teams to come out after the sideline official couldn't get them out for the restart. Then as Kildare pondered would they/wouldn't they, on the far side you had Antrim hiding behind the corner like nervous school kids.
But I don't think either team benefited from it...it's not as if either team has a Colm Cooper or Stevie McDonnell sitting on the bench and chomping at the bit to come on and change the game.
Maybe I'm missing something?

Bloody stupid by both managers if you ask me. They were both acting like spoilt children and possibly increasing the likelihood that a player might have picked up an injury in the first 5-10 minutes of the second half.

Yeah, doesn't make sense to me. Pretty silly stuff really
