On to the players most of us can't live without in the first round of our draft: the running backs.

FRIDAY UPDATE: Chris Johnson ending his holdout, combined with concerns over Arian Foster's hamstring injury, have resulted in a shakeup of our original top six running backs.

Now that Johnson is no longer a threat to miss any games, and Foster is, we have Johnson at No. 2, followed by Ray Rice and Jamaal Charles. We dropped Foster to No. 5, one spot ahead of Maurice Jones-Drew.

If the injury is a threat to keep Foster out of the regular-season opener, it's a threat to bother him all year, which is a huge concern, obviously, for a player we considered No. 1 overall a few weeks ago. We'll have more on the values of Foster and Johnson on Saturday in a column in the print editions and at www.news-herald.com.
