I would play Coleman personally . I really don ' t like GB ' s backfield . All of their WR ' s can have games , but Coleman is a key cog in a high scoring offense and catches balls . I guess if you play in any PPR format I would play Coleman . And he ' s 100 % btw . He ' ll be running full bore . <| sep |> I run him and Urlacher my defense is so lock down I should probably post it <| sep |> You can accomplish this with ES 2015 propertiesclasses . For example class Order get client return this . client set clientval this . client new Clientval class Client get price return this . price set priceval this . price parseIntval You can do the same without ES 2015 using defineProperty and manual prototype chains , but it ' s uglier .
