In Pace's press conference he talked about the Bears' depth at HB with Davis, Cohen, Nall and Patterson. No mention of Mizzell (thank you).
I'm not that confident in Mike Davis so I'm like most thinking Pace might go HB in round 3 - maybe 30% probability. But I know we need a starter at safety next year and I'm not too comfortable with our depth at CB now behind Fuller and Amukamora. So I'd put safety at 25% and CB at 25%. That leaves another 20% for possibly O-line, TE, or edge rusher.
