This draft is pretty deep at RB. Davis fills a need as a backup RB and special teamer. I still expect them to take a RB, possibly high.
OLB and CB have good depth in this draft but pass rushers and CBs tend to go early. By pick 30, it is very possible the steelers will be in a dead area for OLB and CB where all the 1st round talents are gone.
if that happens, i can easily see them taking WR, TE, or even RB if it's the BPA. What if Njoku from Miami, McCaffrey or Dalvin Cook, and Mike Williams or John Ross are sitting there and you take the 5th OLb or 6th CB?
