By far, the most coaches I saw at one tournament was Best of the Best in Massillon. There may have been more coaches at other tournaments, but because all the games were played at the same time at four fields that could all be seen at the same time, there were a lot more coaches seeing each game at Best of the Best.
We also saw a lot of coaches at Compuware. However, not as many attended individual games as I saw at Best of the Best. Oh, I also saw a coach leave a game because she was sitting in the stands, and the fans began ringing cow bells.
At Sluggerfest, my husband's 16U team saw several coaches at games, but we did not see as many at the 18U games. My husband also had coaches at Westerville Warcats and the ASA B State tournament in Strongsville.
Please note that there are four girls on my husband's team that are in regular contact with college coaches. They are probably getting the exposure more because of their emails and letters to the coaches.
