Interesting concept, but I am a believer in shooting with my butt plastered to the baseline (or as close to it as possible). I shoot around 1,500 images a month of HS and youth travel hoops and still have not found as good a perspective as the baseline. Problems do arise in that I have tons of photos of referee's rear ends.....makes me crazy.
The angle part is what I cannot visualize from your description. Are the shots close ups or more of a complete half court shot allowing the viewer to see ALL the players ?
