whether true or not, is that college went to metal to save money- wooden bats breaking more frequently, etc. State could probably afford to use wood if they wanted to, along with everyone else in the SEC, but most people like Marist can't.
The best bet for wood in college is for Louisville Slugger or some other bat company to get a contract with conferences and start out using wood in conference games and go from there, because metal is so prevalent.
Your thoughts about MLB helping college out with this are good, but the fact of the matter is MLB is not going to help college baseball with things like that. A lot of MLB teams would prefer to get a kid out of HS, and then develop them in their own minor league system. For a short period of time, MLB and college are competing for players, so in reality MLB views college as a competitor for US talent, albeit for a short time that it is. A lot of US players have started going to college and are developing, getting more mature and then demanding more money from MLB and are getting it, which is another reason why MLB won't help them out. The fact of the matter is, a lot of MLB people look down on college baseball. Despite the fact that most MLB players go to college.
That's why MLB loves Dominicans- they are cheap, talented, and can be developed in their MLB run academies. They can give a Dominican a 20,000 signing bonus, and the guy thinks he has hit the jackpot, whereas a guy like a Rashun Dixon is going to cost them 300,000 or whatever it was he signed for.
If you ask me, what I think MLB should do is hold coaching clinics for college and high school coaches teaching them how to teach the game. Especially since as I said before that's where a majority of their American players are coming from. To me, that would be more beneficial than buying wood bats.
