There can be any number of reasons a player chooses the JUCO route. For some it may be grades, some want to play right away, for some it may be their only opportunity to keep playing, and for others it is the best route to pro ball. As to why a junior college player may be attractive to a coach at a four year school, that JUCO player has a lot of AB's or IP's against quality opposition. That's experience that a player coming out of high school doesn't have. My older son attended a JUCO because that was the only opportunity he had to keep playing after high school. It appeared after his JUCO career was over that he was through. Applied and was accepted to go to his dream school to just be a student. At orientation,he talked to the coach, got a tryout, and they kept him. The coach told him that they liked his experience - 300 or so college AB's, 2 summers in collegiate wood bat leagues, etc. It's just easier sometimes to project a player that's been around college level competition longer. Now, for the ultra talented, top 200 level high school player its a different story. But for the average Joe playing college baseball that experience really helps out in making him an attractive addition to a team.
