given is RB core I would definitely pick up sproles for hightower,
Sproles has way more upside and is already producing quality numbers. Hightower meanwhile just lost his starting job to Torain which isn't great considering the notion that a lot of people were expecting him to start Until Helu took over later in the season.
Sproles is definitely the more attractive flex than hightower atm
