While there's no need to promote these tournaments (they're full every year with many on a waiting list) I don't understand where the rumors involving (not many scouts) at the 18U come from. That is a highly scouted event. In fact, here are the WWBA tournaments (in order) that draw the most scouts and college coaches.
1. WWBA World Championship in October (Jupiter, FL)
2. WWBA 17U Championship in July (Georgia)
3. WWBA 18U Championship in July (Georgia)
4. WWBA 16U Championship in July (Georgia)
The above are the most highly scouted events involving Travel Teams. While nothing can compare to the first two events, the WWBA 18U is the third most scouted tournament in the nation every year. It's also extremely competitive.
There is way too many talented 16 and 17 year olds playing in that 18U. Then there are a large number of unsigned draft picks and college committed players. These are things that draw lots of scouts and college coaches. It was while playing in the middle of this tournament in 2002 when Zach Greinke signed with the Royals for $2.5 million.
Anyway please, if interested, go to the link below and check out the number of draft picks and MLB players who have played in the 18U. Maybe it will gave a clue as to why it has been so heavily scouted.
You will need to scroll down for quite awhile to see it all.
