I'm linking to a Trib article I found to be illuminating. Yesterday on the live feed someone made the comment that Baltimore's drafting of Oher immediately after us demonstrated that Oher was the best available pick at #22. Never mind the impossibility of knowing that, since once Harvin was off the board, we have no idea of knowing where he would have gone next.
This article, however, makes it very clear that NE was essentially chomping at the bit to get Harvin, and almost certainly wouldn't have traded away #23 if Harvin was still on the board. For those who've heroized Belicheck's unparalleled wisdom in the draft, it also suggests that we've got some brain trust of our own working the front office. Finally, it is worth noting that teams were also dealing with Philly to get ahead of us before they moved up to get Maclin.
All of this, I think, points to the value we got at #22. And, I hope, it is clear how much value we also got at #54, the ideal place in the draft to go after arguably the top RT prospect in the draft.
