Rider got my thought across pretty well. If the poster can be seen from multiple angles (if it were on a floor or a wraparound on a pillar) I think it would be alright to use the text at all angles. The angles could actually deter the slightly interested into becoming not interested, too.
Perhaps you should try the text scrolling *across* the court, as if it is coming at you like the ball would. An idea for thought, that's all
No other critiques though, friend. Good sense of style imo.
