Division 2 scores aren't as bad as you make out. McCallie shot 3559 in the finals last year. That would not have won division 1, but if you line up their scores with the Hixson scores from last years finals Hixson would have won (17.5-9.5).
That's closer than Hixson came to Smyrna in the finals (19.5-7.5). That's also better than Dobyns Bennett shot in their match (3508) , better than Mt Juliet in their 2 matches (3557 and 3498), better than both of Hendersonvilles scores (3417 and 3544), better than Cumberland Gap ( 3059) and almost as good as Brighton ( 3597 ).
The year before that McCallie won Division 2 with a 3788 and Baylor shot a 3549 to lose the final match. In case your calculator is broke, 3788 is not mediocre.
3 years ago Christian Brothers shot 3519 in the finals to win Division 2 and Hendersonville shot 3560 to win Division 1. 41 pins difference in 18 games or about 2.2 pins per bowler.
Division 1 is better than 2, and deeper. But the winners of division 2 the last 3 years would be competiive against Div 1 and those scores were not mediocre and that's not debatable.
And where in the heck did you get a score of 2500? Thats an average of 138 per game. If they ever do break it down into A,AA and AAA and the A wins with a 2500, or anywhere close to that, I'll buy you the ball and bag of your choice.
