Should i pick one of these people up or not?

Donald driver for sure, Wes welker isn't as productive as driver. Welker is good for those short pes which isn't going to help you out much in fantasy. Cel isn't no Tom brady and aaron rodgers is doing pretty well with his first year starting for the packers so driver is still a big threat with the packers despite greg jennings getting most of the looks and catches. Pick up Driver , drop Welker
