NRPMom,
For the best in most levels/ages of baseball, most competitive, I think you should check out
www.bbidallas.org. Many good teams, some travel a little, some alot... For your HS guy, depending on his abilities, Patriots, Knights, Tigers, Panthers are very reputable organizations, with most of the top players in North Texas on their rosters.
BBI ( Boys Baseball Inc.) is the oldest, most well established league in the DFW area. Don't know of any Bear Creek teams that have gone to Mickey Mantle or Connie Mack.
Another alternative is Dallas Mustangs, of Lonestar Amateur Baseball League (
www.lonestaraba.com). Sam Carpenter left BBI many years ago, but has always had very competitive teams, always competes in Mickey Mantle & Connie Mack World Series.
pm, if you'd like more info...
Flower Mound HS is going to State Finals this week (Region 1 5A Champion), so that's definately the school to be in!!
Good luck!
