Nike: Strive for greatness, even if you're not that guy.
Positives: Music. Editing
Improvements: Ball should have been Nike. More shots of the "Goof"
Positives: Clever spot! Great juxtaposition of the contrasting "athletes." Great choice of music in "Yakety Sax!"
Improvements: Camera work and lighting could be a little more interesting.
Positives: Nice idea, even if your not the athlete strive for it. Good contrast in the choice of protagonists.
Improvements: Spend less time with the great athlete and a bit more with the guy who is trying. End with the guy who is trying at least making some progress towards being a better athlete. A bit of payoff.
