I agree Samuel, Jr. would be the ideal value and fit pick at 57. Like you, I doubt he's there. I would guess he goes between 29 and 40. But it IS possible he's there. I think about a guy like Chase Winovich two years ago- largely considered in the 32-40 range and ended up going 77th. So, doubtful....but possible...
I have not been an ILB guy this Draft season but Cox to me seems like he could be a very good value and fit at 57- or after a small trade back. Meinerz after a move back of 5-10 spots from 57 would be good too. Hill as a day 3 center pick would be nice.
I'd feel better about Little at 103 than 88 (with 88 being an edge guy). I think that 88 range is ideal for a lot of the edge guys you've mentioned.
In the end I want to see edge, DL (like you said not a NT type- they have Robinson, SJD and Gaines to plug the interior- they need a Morgan Fox type), CB, and OL addressed by the end of the 4th.
WR is so deep and their need pretty minor. Smith-Marsette from Iowa is a day 3 guy I would like.
