As far as i know, as long as your ball shooting speed remains under 12fps, then you wont have that problem. Dont quote me on this, though, as this is only an observation of other robots, and relative speeds and such.
So anyway, i would check your shooter speed before you complain that the spaghetti doesnt do its job
--oh sorry i think a future comment has nullified this post... i didnt realize that the pushing could have been caused by a swing.
