For return yards, you can play matchups: good offense vs bad defense = lots of return yards for starting kick returners. Examples of return yards vs Minn:
Week 3 (B. Berrian - Chi) : 120 yds
Week 5 (J. Moses - Hou): 120 yds
Week 6 (M. Lewis - NO): 140 yds
For week 7, you may want to look at J. Lewis (Jac) vs Indy who will be returning both kicks and punts.
Also, Wes Welker (Mia) looks like a good play vs St Louis
