Well, your pick dropping a place any time when you forfeit match. For example, if you will finish at 16th place in your league and you will forfeit 3 matches, you will get 4rd pick instead 1st. So 15th team in your league will have 1st pick (of course if it won't forfeit any games )
In manual it is also written: "But, watch out for forfeits because each one means dropping a place in the pick order."
