Well just between the 4 (Edwards, Star, KK and Cole) the amount of snaps could be spread out and keep all four fresh. That could come in very handy when teams try to run three or 4 plays at a time. These guys will be fresh enough to deal with attempt to wear us down.
Cole would benefit most I believe. Gives him time to get acclimated to playing again. He hasn't played a meaningful snap since 2010.
