There are some Legion players that are as good as most anyone in the country. Sometimes it is hard to get them to attend certain events, depending on their Legion team. Some are very strict and won't allow their players to do other things. Some aren't as strict and want to help their players as much as possible.
One of the top 2015 high school prospects in the country plays Legion Baseball. I'm sure he will get a lot of scouting attention. Madison Bumgarner (Giants) was a Legion player, but he also attended the PG National Showcase and made the PG All American Game.
Legion Baseball is great! It is nice to say Brian O'Connor was at a game. But we see him and his assistants many times each year along with nearly every Major College coach. And the events are not in the home state of that many. It would sound kind of small to mention we saw one of them at a game when sometimes there are hundreds of them.
The bottom line is, it's all about talent! Legion definitely has some outstanding talent, but it is very obvious where the vast majority of the talent plays. It is proven every year by the MLB draft and college recruiting lists. So that is where you will always see the largest number of scouts and college recruiters.
Of course if there is a high school age player that has outstanding ability and people know about him, scouts and recruiters will make sure they go see him. They will work it into their schedule. And it won't make any difference if he is on a Legion team or a Travel team or some other team. But they would all prefer to see him playing against others that have the same kind of ability.
