Alex Boone to sign with Vikings; Dolphins target coming off market

The Miami Dolphins have several needs this offseason, with addressing the offensive line near the top of the list. Specifically, the team has to find an answer for their two guard positions, filling the interior of an offensive line that features two Pro Bowlers at left tackle and center and a first-round draft pick from 2014 at right tackle. Unfortunately, one potential free agent target for the Dolphins appears to be off the market now:

The Dolphins were reported to have expressed interest in Boone during the two-day legal tampering period, but no other reports seemed to surface. Boone, who will turn 29 before the season starts, has played six seasons with the San Francisco 49ers, playing on both the right and left side of the offensive line. He has appeared in 77 games with 59 starts.

Miami is also said to be interested in Seattle Seahawks guard J.R. Sweezy. The team could also rely on the Draft to find an answer to their guard problem.

Free agency begins officially at 4pm Eastern time today.
