Tom Pelissero of 1500ESPN.com later reported that the former USC Trojan's contract was worth $16 million.
The Lions made a big splash in inking Bush to the deal. He was one of the top running backs available in the 2013 free-agent class.
Bush expressed his desire to remain with Miami, but with Lamar Miller waiting in the wings, a deal could not be reached and Bush was forced to find his third team in eight seasons.
The Dolphins proved to be a great fit for Bush. After five underwhelming seasons with the New Orleans Saints, the 28-year-old running back posted the two best seasons of his career in Miami—including his first 1,000-yard rushing season in 2011 and over 1,200 total yards in 2012.
Now, Bush will look to put up even better numbers with the Lions.
They'll be getting a versatile back, too. The 6'0", 200-pound Bush has always been known for his abilities as a receiver out of the backfield, and his numbers bear that out. He has had at least 200 yards receiving in each of his seven NFL seasons, and he recorded 88 receptions as a rookie in New Orleans.
The Lions ranked just 23rd in the NFL last year in rushing yards per game, averaging just over 100 yards per contest. Rookie Mikel Leshoure led the team last year with 798 yards and nine touchdowns. They haven't had a 1,000-yard rusher since Kevin Jones in 2004.
From his controversial time at USC to his relations with Kim Kardashian, Bush has been in the headlines off the field for much of his career, but he has seemed much more focused as his career has progressed.
Prior to the 2012 season, he told the Sun-Sentinel that he wanted to win the rushing title. He came up short on that goal, but it shows his drive to be a great running back. Being spurned by the Dolphins should only fuel that fire.
Quality running backs are difficult to come by in free agency—especially under the age of 30. That's exactly what Bush is, and he could prove to be a huge signing once the 2013 season gets under way.
