Urgent NCAA Question

[rainmaker]

I'm working a tournament this weekend that's mostly NCAA women's rules, which I'm not real familiar with. The most important clarification I need right now is what the lane line-up is supposed to be. My partner claims to work D2 but I think (and four coaches agree with me for whatever that's worth) he's got the lane line up wrong. He says it should be four defense, two offense. I thought NCAA was three defense, two offense. Are NAIA rules different from NCAA, especially regarding lane line-up? Would that be why my partner is confused?

Also does what are the coaching and coaching box differences in NCAA compared to FED?

Thirdly, how do I estimate 3-feet for closely guarded? Is it going to be further than I expect, as 6 feet was further than I expected?
