gordon wont lose work to eckler, he is fine. people keep saying that every year and it keeps on not being true. he wont be out there 100% of the time, but even bell, gurley, zeke, and DJ get taken out from time to time. same goes for hunt and ware. hunt wont lose too many touches to ware. ill honestly be surprised if he even is on that team here soon. they have great, and more importantly, CHEAP depth at RB. i sniff a trade of ware. either way, even if he stays, its hunts job.
but to answer the actual question, gordon and fournette. i like all of these RBs. but gordon will be the last true elite workhorse back available, and fournette is knocking on that door as well if he stays healthy and gets the receptions to pair with his insane workload. im ok with any of them though, so long as the first one is gordon. pair any of them with gordon and you will be set at RB for the season.
