If history has showed us one thing in Pro Football, is the fact that even though it's a quarterback/wide receiver driven league, you can't win a championship without a key running game when trying to cross the finish line. So where does one draw the "line" or true value for the running back position, being that most backs in and around the league don't consistently average 900 plus yards per season and 10 touchdowns??? IF the numbers were reversed between A.P and CJ-use-to-play, would Minnesota have done the same in releasing him??? Even though the Vikings, like the Titans, lack big time star power or major talent that at their very best, consistently register average or below average seasons, where do you begin to build an offense around lack luster quarterbacks, offensive lines and wide-outs if the value of the running game is under appreciated and suddenly disappeared. I truly think that NFL franchises will make a fatal mistake in diminishing the value of the running back position, diminishing the market place for the position with "dime-a-dozen" mentalities that "D"-motivate players like Chris Johnson and others in the future. The running back position is the most vital and important position for the quarterback especially. Time of possession is key. Goal line scoring is key. The Titans built their great teams of the past on the shoulders of certain running backs. CJ-use-to-play may not have been worth $8.0 Million Dollars per season, but a consistent player on a team filled with in-consistent talent and play, is worth something that is worth keeping around.
