I'm watching a "classic" game on ESPN from Ye Olde 2007 and I'm noticing a strange mechanic and I'm wondering what is going on.
On the press box side of the field, behind the LJ on the LOS there is an official with an "S" uniform. There are two officials stacked up on the LOS. As far as I can tell, there are still the two deep wings (SJ on the HL side, FJ on the LJ side).
Who is that guy (the second side judge?) and what is he doing there?
