In reading the posts on this thread, it seems to me that most people think the only way HPs can get balls is from the corner goals. Keep in mind the center goals will be feeding back to the HPs as well, so as long as your team is scoring, the other side will never be starved.
New and interesting strategy: build up a ton of points at autonomous mode, get the early lead, stock up on balls and play pre-shot-clock-era basketball where you just hold them until the absolute end of the match. If this means scoring for your opponents, as long as you've got the lead, that's OK. Offense wins games, defense wins championships. Yeah, your RP will be hurt because by design the games would be low-scoring, but if you've got all Ws, who cares?
One more thought: you don't have to have a ball in your hopper (or magazine or whatever) to have control of it - it could be in your alliance station, or you could simply corral the balls in a corner, have 1 or 2 bots in that corner making a fence and defending the balls from the opposition.
So for this strategy, loose ball manipulation would be critical.
