Great mock, and please don't be deterred by the initial burst of rudeness. You guys put alot of work into it (comments for all 7 rounds--wow).
As for the picks:
Round 1: I think this will hinge on whether the reports about Cushing/Matthews are confirmed or refuted by the official reports. Of course, we won't know what those official reports say absent a leak. If they are clean, I think one or the other is the pick, though most here prefer Matthews. If they are not clean, lord knows what we do next, but I have a feeling we grab Wells.
Round 2: I don't think CB is a high-round need--not that our current corners are any great shakes, but I think our current roster is set there. If Unger is still on the board, it would be very, very hard to pass him up.
Round 3: If we went Wells/Unger (admittedly against the grain given our sorry defense last year), then obviously we'd need defense here. Sintim isn't best-suited for a 4-3, but he could be a mean situational pass rusher, something we could really use to allow Antonio Smith to go inside on passing downs. But I think Kruger would be our guy here. But if we took Cushing/Matthews in the first round and don't yet have an RB, Jennings is a good choice, though my UVA bias leans me to Peerman.
Round 4: No problem with Hamlin. I wouldn't mind us taking a WR, but I think local guy Jarrett Dillard fits us better than Massoquoi. Dillard would make an absolutely great slot receiver and may allow us to trade David Anderson to the Broncos for another pick.
After the first four, I don't have much opinion on.
But, again, great work on this mock.
