Who should I keep in my fantasy football league?

In my 12 team Head to head football league, we are allowed to keep three players from last year to have on our team this year. I've already got Steve Slaton and Pierre Thomas locked in at the 19th and 20th rounds but I can choose one more. Do I choose to keep Maurice Jones-Drew in the 2nd round (13th overall) or Eddie Royal in the 21 (last) round?
