Editor's note: Auburn has a rich history of sending players to the NFL. Starting today, beat writer Ryan Black takes a look at each former Tiger that finds himself on an NFL roster (or should be once free agency and training camps shake out). The series will begin with those who have already been in the league for more than one season and conclude with the latest crop of players to land in the NFL, either through the draft or as an undrafted free agent.
Ronnie Brown, Free agent
Position: Running back
Drafted: Taken with the No. 2 overall pick by the Miami Dolphins in 2005
Never miss a local story.
Career stats (through nine seasons): 74 games played; 1,261 carries for 5,328 yards and 38 touchdowns (4.2 yards per carry); 241 receptions for 1,922 yards and two touchdowns (8.0 yards per reception); 7,250 yards from scrimmage
2014 outlook: It's fair to say Brown's best days are behind him. That's not to say it's all his fault. Running back is the most demanding position in the NFL and also has the shortest shelf life. It doesn't help matters that Brown has always had a problem staying healthy. Even so, he'd been a solid contributor for San Diego the past two seasons. Once his one-year was up at the end of last season, however, the Chargers opted to let Brown test free agency. The former Auburn star is still on the market, but one has to think he'll latch on to a team at some point before the season begins, or at some point during the year as clubs seek to add depth at the spot. (New England has emerged as one of the most likely landing spots for Brown, as the Patriots brought him in for a workout last month.)
