Being from NJ, although I'd like to agree with the blanket statement made about the NE players, I can't. Yes, I do agree that there is way too much emphasis on games, it's not the number of games a player plays but the quality of the competition in those games. That leads me to the fundemental skills that a NE player could bring with him, I also believe that "perfect" practice with the "right" instructors can bring about a fundementally sound player. So a combination of high quality games and practice can help a NE player. That being said the kids in warmer weather states have an advantage because they get more of both. Yes, when you look at rosters of warm weather schools the majority of players on those rosters from the NE are pitchers, why? Because they can sharpen their skills all year long (like the kids in the south) but position players can't due to weather. There are scouts and college coaches that believe that if two players (1 from NE and 1 from warm weather) are close that the NE player given the opportunity has greater upside but not all of them believe it.
Another factor to consider when looking at out of state students is the economics of the program. NCAA rules state that baseball is allowed 11.7 scholarships per team, not all teams are fully funded, i.e., they may only have 8 scholarships (baseball money) available to divide their roster, which is usually 30 players.Understand that this pool of money is based on In-state tuition, i.e. 11.7 x $tuition cost, out of state students tuition is significantly higher. So by example, if the in state tuition is $6K and out of state is $18K, a coach can spread the wealth better by getting more in state students rather than recruiting multiple out of state students. If two players are equally talented, and he can give the in stater 25% ($1,500) why would he disrupt is budget by giving the out of stater 25%, i.e., $4,500?
If he can arrange for academic and finacial aid money the player becomes more attractive, if not he will always go with the in state player.
As a side note, when people tell you that a player received a "full ride" ask them if it was baseball money, if they say yes, they're probably lying. A full ride is possible when baseball money is combined with academic and/or financial aid. It is extremely rare that anyone gets full ride baseball money.
