Former Denver running back Knowshon Moreno visited the Dolphins on Friday, but left without a deal. Moreno, 26, was tied for fourth in the NFL last season with 10 rushing touchdowns for the Denver Broncos. He was fifth in the league with 1,586 yards from scrimmage and 12th with 1,038 rushing yards. He was also sixth among NFL running backs with 60 receptions and fifth with 548 receiving yards. But the defending AFC champions decided not to re-sign Moreno and will likely rely on second-year player Montee Ball. The Dolphins last year ranked 26th of 32 NFL teams in rushing. Starting running back Lamar Miller ran for just 709 yards and two touchdowns. Despite putting up solid numbers a year ago, Moreno didn’t have any other reported visits before his trip to Miami. Players became available on the free-agent market nearly two weeks ago. Moreno might have benefited last year from playing in the league’s top-rated offense. Quarterback Peyton Manning had a record-setting season, throwing for 55 touchdowns. While Moreno is much more productive in the passing game than Miller or Dolphins reserve running back Daniel Thomas, Moreno wasn’t better than Miami’s current backs in some facets of the run game. Moreno averaged 2two yards after contact, tied for 39th in the league with Thomas. Miller was tied for 31st at 2.1 yards after contact. Moreno caused 21 missed tackles, which ranked 29th among running backs. Miller caused 22 missed tackles but played 633 snaps to Moreno’s 847 snaps. Thomas, who had just 352 snaps, caused 21 missed tackles. Moreno, former Jacksonville running back Maurice Jones-Drew and former New England running back LeGarrette Blount are the only three proven starters available on the market and none of them are expected to command more than $4 million a year.
