they used to have Matt commentating and Adam summarising but it sounds like Luke Potter is a permanent member of the team now, can't really have three on the mic I'm guessing so they share commentary. Must say Matt is the better commentator in my opinion but Adam is getting better and hasn't been doing it that long.
He is yeah, he's been doing it for years, there used to be a Barnsley FC radio station from the late 90's until a few years ago and Matt has been there ever since it started. I think he's good enough to do national radio or TV as his description is very good although he probably has slightly too much of a Barnsley accent to do that even if he doesn't sound that broad!
