Tom,
I think you bring up a very interesting point. Maybe just like little league, instead of a pitch count there could be a Veteran Inning Count. If under the such suggested age, you may participate later rounds. However if over the certain age, you can only participate in a certain amount of innings before your time is through. This could be cutting edge for younger players and insure the safety of our veteran players or crafty veteran players as some have called it. #fortheveterans
