Ward, definitely.
Lelie, definitely vs KC
Gets a little stickier here.
Bryant - has been doing well recently, and is against a bad SD pass defense
Houshmandzadeh - Cincy's offense is clicking, but Bufalo has a very good defense
Williams - Not quite playing like the beginning of the year, but is against Minnesota
Burlseson - Playing a bad defense, but I think the Vikings are gonna try to get back to Moss
I'd say Ward, Lelie, Bryant, Williams. Although MAYBE houshmandzadeh over Williams. That's a tough call.
