I don't get the "they play all the time on small fields" argument. Yes, and Stoke plays on as small field and QPR plays in a tiny old venue. But were they to meet in the FA Cup final, they'd be playing at expansive, state-of-the-art Wembley.
Look. Your CHAMPIONSHIP weekend SHOULD be a showcase event. I think it's great that Gilbert is making the effort to host. Kudos to them! But I also think there are better, FAR more appropriate places to play a SHOWCASE event like the SCHSL Championships.
The two concepts are NOT mutually exclusive.
