Y ain't NCAA baseball as alluring as the MLB or 2 certain other NCAA sports? Metal bats? Slow pitches?

Hey, how come "America's pasttime" hasn't stirred up excitement @ the NCAA level? Is it those metal bats & slow pitches? I'm kinda wondering y Rice, UC Irvine, CSU Fullerton, etc. ain't as attractive 2 future big leaguers as USC, FL, OK, etc. is 2 future NFLers or Duke, MD, UCLA, CT, etc. is 2 future NBA guys. & has the NCAA, certain universitys, or big leaguers who went 2 such colleges seriously tried 2 market or promote college baseball?
