To become the defensive coordinator at Fremd.
So, as a Palatine fan I don't like this for a couple of reasons... If he was gonna be available I wish he would have come to Palatine as the head coach. I think Olsen will do a good job, but a guy with Pearlman's resume doesn't come along very often. Having been one game away from playing for the Class 8A championship the last two years, he might have been that guy to get them the next step and it is a solid program base to start with, which I don't think he ever had at Wheeling.
He could have come to Palatine as DC too, since Splitt had run the defense for years and now we need a replacement on that side of the ball too(We got Donnelly back as OC, maybe we can get Petricca to come back for DC???

)
Secondly, Fremd's been a "meh" program under Sponsel while (their crosstown rival) Palatine has won 5 out of the last 6 MSL West titles. I can only wonder if this DC is a "biding time" thing and eventually Pearlman becomes the head coach at Fremd.
