It wasn't a real "radio" broadcast of the games. It was a feed of the TV broadcast. They often said things like "and now we'll get another look at that play...."
I was pretty happy that all the games were on both radio and TV so I'd have the option to check them out.
I listened to about 1/2 of one game on 98.5 and then watched one entire game on WSBK on TV.
While the production, broadcasters, etc were not top notch, considering it was all pieced together by people not doing it on a weekly basis it wasn't bad. Also, not sure if they switched 1/2 through the day or not but Felger/Zolack called at least 2-3 games back to back (if not all 6) which has to be hard to do, especially since neither are regular play by play guys.
I'm not a fan of 98.5 or Felger, but all in all I think everyone involved did a great job covering a full day of high school football.
