The Dolphins are no longer likely to pick a quarterback in the first-round of the NFL Draft according to Barry Jackson of the Miami Herald. Several factors conspired to practically ensure that Miami will address a different position with the eighth or ninth pick of the first round, barring a trade-up with St. Louis for the No. 2 choice, and the right to select Baylor’s Robert Griffin III. With Matt Barkley and Landry Jones deciding to remain in school, Griffin soaring up draft boards, and the Dolphins winning more games than quarterback-starved Cleveland and Washington, there is no quarterback considered worthy of selection in the Dolphins’ first-round range. And that means Miami’s best options at that spot figure to be an offensive tackle, a defensive end or a linebacker such as Boston College’s Luke Kuechley. Cornerback is not out of the question.

If Griffin is gone, not worth it. Draft needs first, Moore did a pretty good job with the team that was around him, so if you don't grab a QB early, you can grab one late that you can hope to mold.
I would love to trade back with a team like the Bengals if they absolutely have to get a guy like Richardson is he were to fall to the Dolphins. Then they could take a guy like DeCastro and Osemele and Foles. Let Foles sit and learn. That would shore up the entire line and would be a beast.
