Brain teaser
 

Should be fairly easy if you know your rules, but might not be as easy as you think...

From a match I had last week...here's how a team's front row lined up. By rule, how many overlaps are there, and who is overlapped? (sorry, trying to space things out, but HTML isn't cooperating. The abbreviations are approximately where each player was standing).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(net)
.................................................. .......................RF (right front)
.................................................. ....................................LF (left front)
...........CF (center front)

One... LF & CF.

Agree with BBS.

Correct. Even though RF is lined up as CF, there is no overlap there by rule.
