If your #3 guy keeps losing, over and over, bad, and you dont switch them to a lower position, other teams can protest your lineup.
Baylor a few years back had interchangable 1-4 guys. But no one could protest them during the year, because they were that good. If you have your #3 guy all of a sudden play #6, you will get called out on it.
Of course, there are always coaches that say "Well, my #1 guy (who cant win a match) always beats my #2 guy (who never loses)." Its almost more ethical than anything.
