I mean, a running back to compliment Gore, not replace him. If they are going to try to dominate people with a running game, they need 2 backs, especially since Gore is not really a ball control back and there's a reasonable chance his most healthy playing days are behind him.
DeShaun Foster is not that back. If we go into next season with Gore and Foster as the 2 backs, they will not be able to run their system effectively.
Should they draft one? Drafting one in the 1st round probably wouldn't be ideal considering all the other holes they have on the team, although both Moreno and Beanie Wells are probably going to be studs (with Wells as the better compliment to Gore imo.)
Are there going to be any bigger backs who would fit well next to Gore later in the draft? Any names?
