Great discussion and I don't think TSSAA will sanction anytime soon. Too much on their plate as many have listed in other posts and too many issues.
Private Schools are better because of better resources, more money and coaching. The bigger problem exists with feeder programs, long term stability of coaching and continuous stable resources at those levels. MBA, and the other private schools have enormous amounts of resources, money, talented and paid coaching staffs and years of stability. They have similar resources at their middle school AND EARLIER levels. Until public schools match that level of money, facilities, coaching and steady feeder programs their ability to compete with the KINGS of lacrosse will be limited.
Also, many quotes about Franklin being around as a long term program and why not playing Div 1? The facts: Franklin is in its third year of competition and with its second coach. The kids at that school started with 6 upperclassmen and 16 Soph and Frosh three years ago and have improved because of the time playing together and the ability to get better by having more playing time. Hardly a long term program when considering the other schools in Div 1 and Div2.
