Let's look at the other RB's besides Maroney drafted in the first round past 5 years and how many 1500 yard seasons they have produced:
2004:
1(24) Stephen Jackson, Oregon State. Considered a top NFL back. One 1500 yard season out of 5 so far. Currently on pace for 1467 yards this season.
1(30) Kevin Jones, Virginia Tech. Zero 1500 yard seasons so far. One 1000+ yard season. Currently on Injured Reserve.
2005:
1(2) Ronnie Brown, Auburn. Zero 1500 yard seasons. One 1000 yard season. Dinged up a lot. Very effective in the Wildcat.
1(4) Cedric Benson, Texas. Zero 1500 (or 1000) yard seasons. Considered a total bust in Chicago, has rejuvenated his career in Cincinnati. Currently on pace for 1468 yard this season.
1(5) Cadillac Williams, Auburn. Zero 1500 yard seasons. Started hot but has been injured a lot. One 1000 yard season. Currently on pace for 764 yards this season.
2006:
1(2) Reggie Bush, USC. Zero 1500 yard seasons. Considered one of the 3 best backs this decade coming out of college (with Adrian Peterson and Darren McFadden). Has never rushed for over 600 yards. Currently on pace for 592 yards this season. Fine all-purpose weapon.
1(28) DeAngelo Williams, Memphis St. One 1500 yard season (2008). Did very little his first 2 years before breaking out last year. Currently on pace for 720 yards this season.
1(30) Joseph Addai,LSU. Zero 1500 yard seasons. Ran for just ove 1000 yards his first 2 seasons, then got dinged up and hasn't been the same. Currently on pace for 732 yards this season.
2007:
1(7) Adrian Peterson, Oklahoma. One 1500 yard season (2008). Ran for 1341 years as a rookie and 1760 yards last season. Considered the top back in the NFL. Currently on pace for 1648 yards this season.
1(12) Marshawn Lynch, Cal. Zero 1500 yard seasons, but ran for over 1000 yards his first 2 seasons. Suspended for the start of this season.
2008:
1(4) Darren McFadden, Arkansas. Zero 1500 yard seasons. One of the most heralded RB prospects this decade. Ran for 499 yards as a rookie. Currently on pace for 584 yards this season.
1(12) Jonathan Stewart, Oregon. Zero 1500 yard seasons so far. Ran for 836 yards as a rookie. Currently on pace for 396 yards this season.
1(22) Felix Jones, Arkansas. Zero 1500 yard seasons so far. Ran for 266 yards as a rookie while missing 10 games to injury. Injured again this year - must be made of glass. Currently on pace for 848 yards this season.
1(23) Rashard Mendenhall, Illinois. Zero 1500 yard seasons so far. Ran for 58 yards as a rookie before going on IR (must also be made of glass). Currently on pace for 840 yards this season.
1(24) Chris Johnson, Eastern Tennessee. Zero 1500 yard seasons so far. Ran for 1228 yards as a rookie. Currently on pace for 1736 yards this season.
2009:
1(12) Knowshon Moreno, Georgia. Currently on pace for 996 yards in his rookie year.
1(27) Donald Brown, Connecticut. Currently on pace for 528 yards in his rookie year.
1(31) Beanie Wells, Ohio St. Currently on pace for 284 yards in his rookie year.
So including Maroney, 1st round draft picks in the past 5 years have rushed for a total of 3 (1 Stephen Jackson, 1 DeAngelo Williams, 1 Adrian Peterson) 1500 yard seasons out of a total of 43 complete seasons to date, with 2 more (Peterson and Chris Johnson) currently on pace for a 1500 yard season and 2 others (Jackson and Cedric Benson) within reach.
Many of the RBs listed have been dinged up a lot and missed considerable time due to injuries (Ronnie Brown, Cadillac Williams, Felix Jones, Rashard Mendenhall). Clearly these guys must all be made of glass.
So far, only Adrian Peterson and Chris Johnson look like perennial 1500 yard franchise RBs.
Clearly Maroney's a bust when compared to the other 1st rounders listed here.
Who said anything about 1500 yards rushing?
What ever happened to the all-purpose back?
Almost every single one of those backs is sharing the load with another back as well, some are sharing the load heavily, so they will never even approach that #, and that is the decision of the franchise.
SJ plays on a PATHETIC Team, I'm surprised he gets 500 yds
KJ- Played on a really pathetic team, with pathetic coaching and management, went to the Bears as a #2- Got Hurt- on IR
RB- Been dinged- VG RB, Mediocre teams for the most part- no QB to scare anyone.
CB- Held out all of training camp in rookie year, had to fight to get touches with Thomas Jones for next 2 years, suffered a sprained MCL in 05, season ending ankle inj in 07.... I guess he's made of glass.....Doing pretty well with a real honest chance at being the #1 in Cincy
Caddy- Gruden hammered him into the ground his rookie season, got SERIOUSLY hurt, and it's a miracle he's even playing.
ReggieB- Never figured he'd be a 1500 yd rusher, anyone that thought he would be needs to have their head examined. Great ALL Purpose back- will most likely have more yds receiving than rushing- massive time share.
DW- Never got a full time shot, finally given a bit of the reigns last year and exploded, even in a time share. Playcalling this year has been very suspect, and delhomme is killing his chances by throwing picks and the team falling behind- VVG RB, can take it to the house from anywhere on the field.In a time share with JStew.
JA- Plays in a finesse offense, throw 1st- time share, injuries have hurt him. More like a Reggie Bush than an AP.
AP- Stud, even on a bad team when they new he was getting the ball....
Lynch- Still unproven to me, bad team with bad management and lousy Qbs...
DMC- Unproven, on a HORRENDOUS team and management is AWFUL, with the worst QB in the last 20 years.in a massive time share with 2 other guys...dreadful situation that will never right itself while he is on that team with AD still alive..
JStew- Unluckily behind a stud in DW, has been hurt more than not since becoming a pro. Good effort back, with FT Touches could become a VG back.
Mendy- From outsider POV he seems immature, as even his coach benched him week3 because he was missing "details", got a chance as the featured back for the first time against SD in week4 and did NOT disappoint, ran for 165 and 2 tds, and was hitting the line HARD and fast, some of the creases he ran through hard weren't large, or even open fully yet, but he saw a small crease and exploded through it.
1 Week against a suspect D, but his runs sure looked good.
Missed almost all of last year due to injury, and didn't really get touches this year because WP is the #1 in Pitt, and Tomlin is very loyal to his players.
CJ- Ran like the wind in his rookie campaign, and was a VVG back. Shared time/carries with Lenwhale White, and continues to do so in 2nd year. VG back.
The 3 rooks either split time, or get virtually no carries yet(beanie-passing team-HT in 2nd year).
Brown looks VG in limited touches
Moreno- Seems to be doing good, I think Buckhalter is better at this stage of their careers.
Beanie- Not getting many touches....
