This is what Mel Kiper would do if he was our GM. I thought some people here might not have an ESPN Insider subscription, so I thought it was worth posting. Looking at this, I am glad ole' Mel is not our GM..
Top needs: CB, WR, C, DL
Round 1 (30) CB Lamarcus Joyner, Florida St.
Round 2 (56) C Marcus Martin, USC (from KC)
Round 2 (61) WR Josh Huff, Oregon
Round 3 (77) DT Dominique Easley, Florida (from TEN)
Round 3 (94) CB Nevin Lawson, Utah St.
Round 3 (100) QB/TE Logan Thomas, Virginia Tech (Comp)
Analysis: This draft sequence is something of a bet that the offensive line remains relatively stable if I get the needed help at center (Martin), and that even if NaVorro Bowman takes his time coming back, the linebacking corps will remain solid. The early priority is grabbing a capable corner, and Joyner can provide impact right away as a Tyrann Mathieu-type, a guy who can play corner, particularly in the slot, and provide time at safety. Huff isn't a burner, but he's more of a developmental project than some other receivers who will be taken in this range. Easley is an early-first round talent coming back from yet another knee injury, but at this point in the draft, getting that kind of talent is worth the shot. If he can spell Ray McDonald and Justin Smith effectively, everyone gets better. I like Lawson as a sleeper and possible corner help, and I love the idea of letting Jim Harbaugh work with Thomas as a developmental project at either QB or tight end. (Thomas really could pull off the conversion if he wanted to.)
