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.

Quick slants: The electric Charles has totaled 2,587 yards rushing, 85 receptions, 765 yards receiving and 16 TDs the last two seasons. He has averaged 6.2 yards per carry in that span. ... Gore has missed a total of nine games the last three years. ... In three years with the Falcons, Turner has a combined 39 TDs, but only 23 receptions. ... The Rams' Jackson, who really has only had one big season, has a combined 10 TDs the last two years. ... The Panthers' Williams had a huge 2008, but has eight TDs in 19 games since. ... The Lions' Best had five of his six TDs in his first two games as a rookie. ... A possible sleeper is the Packers' Starks, who rushed for 315 yards in four playoff games last season. He could take over for Ryan Grant as the featured back at some point this season.

Before we get to the rankings for the most important position in fantasy, let me be master of the obvious: It's good to have the No. 1 overall pick in your league.

This year, it's almost as crucial as it was during the LaDainian Tomlinson glory years.

And the reason has nothing to do with the expectation that Adrian Peterson will outscore every other running back this season. In point-per-reception leagues, he almost certainly won't.

It instead has everything to do with the fact that there's no clear-cut No. 2 pick behind him. I'd give the slightest of edges to Matt Forte over Maurice Jones-Drew, but owners in non-PPR leagues certainly have to target Michael Turner.

There are questions regarding every back on this list. Will Forte and Slaton experience a sophomore slump? Will Turner and DeAngelo Williams be nearly as great as they were in 2008? Will the slimmed-down LenDale White cut further into Chris Johnson's scoring? Will Steven Jackson stay healthy? Will L.T. continue to decline?

There are no such concerns with Peterson, who is the football version of Albert Pujols. Take him first, and don't even consider anyone else.

In PPR leagues, Peterson was outscored by the likes of Williams, Forte, Jones-Drew, Turner, Tomlinson, Slaton, Brian Westbrook and even Thomas Jones last season. That was because of two factors: His less-than-average receiving totals (21 catches for 125 yards) and his decrease in touchdowns (from 13 as a rookie in 2007 to 10 last season).

Regardless, Peterson rushed for 1,760 yards in his second season, averaging 4.8 yards per carry, and with a decent -- albeit aging and waffling -- quarterback, the addition of Percy Harvin and a good offensive line in Minnesota, you should have every reason to believe he will average more than 100 yards and one TD per game.

Will that be enough to vault him to the top of the scoring leaders in PPR leagues? Probably not. But you don't want to miss with the top overall pick, and Peterson shouldn't disappoint you in any format.

QUICK SLANTS
Turner, who has 17 catches in 75 career games, is even less of a help in the receiving department than Peterson. ... With Fred Taylor in New England, Jones-Drew's touches per game should increase from its absurdly low 2008 total (16.2) to at least the low 20s. ... The Rams' Jackson always produces, but he's also frequently hurt (12 games played in each of the last two seasons). ... Gore has a combined 157 catches the last three years. ... The Cowboys' Barber averaged 14 TDs per season in 2006 and '07. ... The Jets' Jones scored only two TDs in 2007. ... In 20 games played the last two seasons, the Chiefs' Johnson has nine touchdowns. ... The Browns' Lewis (1,552 total yards and 11 TDs in 2007) could provide value as a third running back, but not if he repeats his 2008 production. ... The Bengals' Benson has 12 touchdowns in 47 career games. ... A possible sleeper: Buffalo's Fred Jackson, who should be the featured back with Marshawn Lynch suspended for the first three weeks. Jackson is more of an asset in PPR leagues.
