I am in a keeper league that gives points on return yards and return touchdowns. As of now, I have Portis as my keeper, but his value seems to be slipping more and more each day. I have two weeks to decide my keeper and it is a toss-up between Portis, Calvin Johnson, DeSean Jackson and Leon Washington.

I am only considering Jackson and Washington because of the return points.

12 team league with 17 roster spots: one QB, two RB, three WR for starters.

Any advise out there?
