Should the Dolphins, Bills trade back?

NFL observers have debated the past few months trying to figure out what the Miami Dolphins and Buffalo Bills should do with their top-10 picks. Miami picks No. 8 overall, while Buffalo holds the No. 10 pick.

But should one or both teams consider trading back in the draft? It's a valid option if either team can pull it off.

The key would be an enticing player fall. The two that come to mind are former Alabama running back Trent Richardson and former Texas A&M quarterback Ryan Tannehill. If one of these players fall, the phones should be ringing Thursday night in Miami and Buffalo.

Richardson is a top-five talent. But recent knee surgery and the lesser importance of running backs at least make it possible that he falls to Miami at No. 8. If that's the case, several teams in the teens could be interested in moving up.

Tannehill is another hot prospect who shot up the draft boards. Initially viewed as a late first-round or early second-round pick, Tannehill has impressed scouts in the offseason and could go as high as No. 3 or No. 4.

But if there isn't a trade with Minnesota Vikings and the Cleveland Browns pass on Tannehill, he probably will be there at No. 8. That would put Miami in the position to draft Tannehill or pass. Most project the Dolphins will take the quarterback. But if Miami passes and Tannehill falls to Buffalo, several quarterback-needy teams could be ready to pounce.
