Description: ESPN's John Clayton suggested Miami as a possible suitor for free agent running back Darren McFadden.
Insight: Starter Lamar Miller was a relative disappointment for the Dolphins last season, rushing 177 times for 709 yards in 16 games. It might be hard for McFadden, who is also being pursued by the Bengals, to find more than a one-year deal given his recent injury history.
Description: According to the Denver Post, the Broncos believe it's time to take the training wheels off their young running backs, Montee Ball and C.J. Anderson.
Insight: Knowshon Moreno is a free agent and will likely be let go after picking up 1,500+ yards from scrimmage and 13 touchdowns in 2013. Ball ran for 4.7 yards per carry on 120 attempts and finished with 559 rushing yards and four touchdowns. He'll be a high-end RB2/low-end RB1 in 2014.
Description: Falcons running back Jason Snelling announced his retirement on Tuesday. SOURCE: Jay Adams, AtlantaFalcons.com
Insight: Snelling was Atlanta's third-string back last season behind Steven Jackson and Jacquizz Rodgers. He'll finish his career with 168 catches, 1,249 receiving yards, 1,420 rushing yards and ten combined touchdowns in 96 appearances. He played his entire career with the Falcons.
Description: Geoff Hobson of bengals.com writes that RB Giovani Bernard "no doubt" will near 300 touches in 2014.
Insight: Former Cincinnati offensive coordinator and committee proponent Jay Gruden is now the head coach in Washington, so Bernard should have a chance to control the backfield in his second season. He had 695 rushing yards on 170 carries, 514 receiving yards on 56 catches and eight total touchdowns as a rookie while splitting time with BenJarvus Green-Ellis. Gruden stubbornly stuck with the "Law Firm" even though he rushed for just 3.4 ypc.
Description: Former Steelers and Cardinals halfback Rashard Mendenhall is considering retirement.
Insight: Mendenhall hinted at calling it quits in a blog post he wrote for the Huffington Post. This would be a disappointing end to what was once a promising career. The first-round pick from Illinois logged back-to-back 1,000-yard seasons in 2009 and 2010 but hasn't come close to that level of production in his last three seasons (687 yards, eight TD in 2013).
Description: Houston running back Arian Foster (season-ending back surgery on November 15th) is progressing on schedule, according to GM Rick Smith.
Insight: Foster should be ready for training camp, but his inability to stay healthy has to concern fantasy owners and the Texans. Ben Tate is likely to leave in free agency so expect Houston to draft a running back not long after selecting a quarterback of the future.
Description: Minnesota running back Adrian Peterson (groin surgery) is on track to be ready for April OTAs.
Insight: Peterson followed up his MVP 2012 campaign with a still respectable though not up to expectation 1,266 rushing yards and 10 touchdowns in 2013. If the Vikings can find a passing offense to balance it out, he should be good for a few more years.
Description: Seahawks halfback Marshawn Lynch will plead guilty to reckless driving. The charge stems from a 2012 DUI arrest. SOURCE: Terry Blount, ESPN
Insight: His punishment will be a fine and two years probation. Lynch's lawyer believes he'll be able to avoid suspension by the NFL. Assuming that's the case, Lynch (1,257 rushing yards, 12 TD in 2013) should be a top-ten selection in all fantasy leagues this summer.
