I'm amazed that the annual playa rugby match doesn't turn more physical. If the ruggers can avoid pounding each other into the playa, I have high faith the flag footballers will probably do the same.
That said, I'd love to play, though I'm almost positive I won't be able to come up with 4 others. Anybody want an obnoxiously tall, lightning fast guy for their team? I play a mean wide out.
