Some key numbers from ESPN Stats and Info on Chris Johnson, who was released by the Titans on Friday:
Four-digits: Johnson's current streak of six straight 1,000-yard seasons is the longest active streak in the NFL. No one else has a current streak longer than three years. Frank Gore and Marshawn Lynch have done it the last three seasons.
Two thousand: Johnson is one of seven players in NFL history to rush for 2,000 yards in a season. The list: Eric Dickerson, 2,150 yards in 1984; Adrian Peterson, 2,097 in 2012; Jamal Lewis, 2,066 in 2003; Sanders, 2,053 in 1997; Terrell Davis, 2,008 in 1998; Johnson, 2,006 in 2009; O.J. Simpson, 2,003 in 1973 (14 games).
Bell cow: Since 2008, Johnson had 69 percent of the Titans' rushing yards. That's the highest percentage of his team's rushing yards of any player in the league. Peterson had 66 percent for the Vikings, Matt Forte had 63 percent for the Bears, Maurice Jones-Drew had 59 percent for the Jaguars and Steven Jackson had 58 percent for the Rams.
Losses and no gains: Johnson has been tackled for a loss or no gain on 410 rushes since he entered the NFL in 2008, the most during that time
The list: Jones, 1.23; Tomlinson, 1.42; Johnson, 1.45; Ray Rice, 1.47. (Minimum 500 rushes.)
YBC: While Chris Johnson has struggled with yards after contact in the last five seasons, he has the fifth-most yards before contact since 2009. That list: Jamaal Charles, 3.76; C.J. Spiller, 3.35; Reggie Bush, 3.12; LeSean McCoy, 3.12; Johnson, 3.07. (Minimum 500 rushes.)
Runs of 20 yards or more: Johnson had progressively fewer 20-yard rushes in each season since his huge 2009 campaign: 22 in 2009, 13 in 2010, 11 in 2011, eight in 2012, five in 2013.
Against loaded boxes: Johnson runs versus loaded boxes year-by-year: 59 (4.56 average), 68 (5.44), 51 (4.31), 36 (3.42), 46 (7.28), 44 (3.91). That's 44 of 279 in 2013 or 16 percent.
