I'm confused as to how the keepers work in this league.
Essentially, any player drafted 6th round or later can be kept. The following year you may keep up to three of those players getting them two rounds ahead of where you drafted them.
So if you draft Peyton Manning in round 6, you can keep him and he'll count as your 4th round pick in 2013. Likewise, Brandon LaFell, if drafted in the 15th round, can be kept in the 13th the next year.
