Chiefs or seattle defense rest of year PPR?

May have a chance to get seattle and drop chiefs defense as they are coming off a bye and chiefs is week 10-also have tyreke hill as he scored a special teams td last week for me -what should i do as i have no room to add on my bench-help me out-thank you!!!

No advice on this for me? Alny and all would be appreciated-may drop E sanders and pickup P Garçon and drop Reed for Seattle D and just go with J Graham as my TE rest of year and pray he stays healthy-
