Just going off the draftnik stuff I've seen, I'd be quite happy with Warren or Loveland. The latter has been showing up in mocks quite a bit recently since he's a more capable outside receiver who can beat man and play as a true Y in-line (a bigger Sam Laporta w/ better blocking). I really like Derrick Harmon too - I've been biased ever since I heard Nate Tice compare him to prime Akiem Hicks. He's got unreal size and is valuable in both the run & the pass. Poles will love those measurables. If there's no trade down opportunity - I'd rather take that than gambling on a Shemar Stewart. There are several projected Dennis Allen type edges at picks 39 & 41. Landon Jackson, Bradyn Swinson, JT Tuimoloau, Jordan Burch, etc...
They can take RB with the other 2nd rounder or wait and grab whomever is best at 72 e.g., Dylan Sampson, DJ Giddens, RJ Harvey, Bhaysal Tuten, Damien Martinez, Devin Neal, etc...
It was mentioned awhile back, if the Bears would reach on a RB and it's a guy they just had in for a top 30 visit in Omarion Hampton. That would be my one of my least desirable moves if they stick at 10.
