I only use it to put one CB on one WR. It only affects man coverage, so I usually put the guy with the best man rating on their best WR. I'll also use it to put my fastest CB on their fastest WR, if there's a mis-match otherwise.

I find that anything else does cause problems like having your LB at CB depending on the formation. Once I start giving mulitple assignments, it seems to really take defenders out of position.
