I think a trade back is likely also. The Cards only have 5 picks, correct? I can see Monti wanting to acquire more. I don't think a trade back is a bad idea. The talent level is pretty even in the mid 1st to mid 2nd rounds. The kids from Marshall or Ole Miss in the late 1st/ early 2nd could easily turn out better than Pearce, Walker or Williams.
At edge after Carter, I'm not sure where the big talent drop off is in this draft. To me, after Carter, McMillan, Hunter and maybe Graham, you could make an argument for numerous guys at each position of who is best and who the next 4-5 are.
