There is absolutely no hype at all in this film. Neither of the two players, who were the subjects of the film were phenoms or can't-miss prospects. If anything, the film is about the prospects who do miss; the ones who give their best shot, but fall short of their goals to make the majors.
I know firsthand how they feel; I had my shot, and didn't make it out of Double A ball. I could hit for average, but just didn't have the power to be a major league first baseman. I wound up settling to be a scout for the Yankees for a few years, and then I just left the game completely. I enjoyed my time playing, but those 10 and 12 hour bus rides were just too much for me to continue. Playing minor league ball is not glamorous, as the film amply shows,
The subjects in the film showed flashes of brilliance, and, at times, promise for the future, but it takes much more than that to make the bigs. The film leaves us hanging about one player, Johnny Drennen, but it does a very nice job of fleshing out the life of Tony Schrager, and his transition to non-baseball life. Sadly, Drennen did not make the transition as well as Schrager, as he was banned from baseball for 50 games for drug use.
If you want to see what life is really like as a drafted baseball player, then this film will certainly make it very clear for you. Highly enjoyable filmmaking.
