Most NFL front offices really are pretty savvy (Al Davis and Jerry Jones always exceptions). They can't predict injuries, and at times can't foresee team chemistry and get blinded by physical skills vs. character, but generally want to make the smart long-term decision. The draft is like any other "market" driven by supply and demand. This year, OT talent is deep, but demand has never been greater, so they will go quickly. If you don't take one with your first pick, you may be looking at the 10th best prospect in round 2. QB talent is shallow, but demand is spotty, so they won't go quickly, maybe only 2 in the first 2 rounds. Crabtree is talented, but there isn't perceived to be that much long-term difference in potential at this high risk position into round 2 or 3. You can't say that about Corners. There is a chasm between the top corners who could start as rookies and the rest of the field.
The Lions will follow Miami's lead and fill their greatest need, OT with Monroe or Smith.
The Rams will do likewise, taking the other to help the rushing attack.
The Chiefs would love Monroe to fall to them. Afterall, Brandon Albert moved to guard at Virginia due to Monroe, and Albert is now KC's starting left tackle. In the end, with Monroe off the board, they will choose to shore up the pass rush with the best available. I think it will be Curry, as there are no DE with quite as much potential. KC traded up last year for Mayo, and that turned out to be a great call.
Seattle will shore up the 28th rated pass defense with the best CB (since there are no Safeties that warrant this pick) Malcolm Jenkins, who will start opposite Trufant.
(Expect a WR and SS in rounds 2 and 3, with O-line getting help in round 4)
Crabtree winds up at Oakland, completing Al Davis Trifecta including Russel and McFadden.
The Niners pass on QB until round 2 or 3 and go DE with their first pick.
The Jets grab Stafford who is the first QB taken.
And the planets are re-aligned and the world makes sense again.
