It probably is somewhat dependent upon your League Settings, but IDP's who return kicks and punts get those points in my league with rtn yds. They score big even though there's no scoring column showing them.
Brightful and Rossum are the two high scoring DB's in my league with return yards.
BTW, how is Jimmy Wilkerson doing in your league:
“The Green Bay Packers never lost a football game. They just ran out of time.”
