I think it probably helps that your coach is Vin Lannana, when you're trying to get meet entries against the other 3:53-3:55 guys. But, he's not undeserving of the spot, and there's no way he bumped someone like Strand, or even Green or Sahlman.
At this point, Strand gets in any domestic race he wants. I guarantee you if Strand rocked up unannounced 30min before the race and asked for a spot they'd put him in.
