I play in a league where you can keep one player indefinitely. It is a 12 team league, half-point PPR, and starts 2 WR (not 3 like many leagues these days. I have the 9th overall pick (2nd round), so whoever I don't keep won't make it back to me, and all of the stud RBs (Bell, Gurley, Zeke, Johnson, Barkley, etc.) will be kept or drafted before my first pick.
