Fantasy Football.. Keep Ahman Green or Chester Taylor ??

Ok, here's the deal.. I have Marshawn Lynch and Reggie Bush.. but Lynch has a bye in week 6 so I only have two backups.. Chester Taylor and Ahman Green.. Taylor plays Chicago and Green plays the Jaguars in week 6.. We are in week 5 but I need to pick up a TE.. which of these two running backs should I stay with and why??
