FWIW - We have seen Walker Kelly pitch against one of the top lineups possible. (Chet Lemon Juice) They are far from average having nearly every player heading to top DI programs including U of Texas. They also have several potential high draft picks on that team. I think everyone would call them more than a legit program.
Walker Kelly pretty much dominated that line up. Everyone has a bad day once in awhile, but I don't think Walker will have many of those at the high school level. JMO
