First of all, you've provided too much (mostly unnecessary) information. For the purposes of what I really know about this film, you've indicated that an athlete, who lives in the shadow of his alcoholic father's faded glory, is mentored by an ex-olympian. That's it. It's not a story, that's the set up for the story. What is the protag's goal, what are the forces opposing him, and what are the stakes if he fails?
Also, names are completely unnecessary in a logline, so I'd drop them.
Finally, this logline is unclear who the main character is, because you start with Jobe, but the only person you've indicated actually has a purpose in the film is Harry White - who must encourage Jobe to perform at his best. Presumably it is Jobe's story, so I'd be careful about describing the mentor character's arc.
