Based on real life coach I really think that Brad Pitt hit the home run, expressing not only the core of baseball but the core of human kind evolution, where methodologies and inspiration come together for a perfect result.
Keep your eye on the ball. The play done by Pitt is actually straight forward and very convincing with only one minor adjustment: I would prefer it with some weight on him. He does look the part.
The story is a real life based but the way it was said was the convincing part. Brad Pitt is very convincing with all the superstitions of a ball player.
Almost forgot, Hoffman is as always a perfect man for the job. You can see that even if it is a secondary role his act and studies of the character is really showing off.
On the funny side, one conclusion can be that only a divorced man can focus on his job 110% 🙂
