San Francisco 49ers guard Mike Iupati is one of the many high-profile free agents this offseason who is expected to change teams. The three-time Pro Bowler has a long list of suitors as he has proven to be one of the best run blockers in all of football.

So which teams are after this mauler in free agency?

"Continue to hear SF, OAK, NYJ, BUF among those in the hunt for Mike Iupati. Would tend to think he's moving on from 49ers at this point," Jason La Canfora of CBS Sports tweeted.

The Raiders have almost $65 million in salary cap space and are determined to add difference makers on both sides of the ball this offseason. After ranking dead last in rushing last season (77.5 yards per game), Iupati is precisely the type of addition that can help address glaring weaknesses. However, as La Canfora noted, the Raiders will have stiff competition for his services, especially from the Jets.

"The Daily News has learned that the Jets are targeting three-time Pro Bowl guard Mike Iupati to improve a weak interior line in need of a facelift," Manish Mehta of the New York Daily News wrote. "The Jets were serious players for Broncos guard/tackle Orlando Franklin, according to sources, before the veteran agreed to terms on a deal with the Chargers on Sunday."
