I think what you posted does not support this position at all!
All of the pre-draft rankings you posted seemed to be MORE accurate than the post draft (situation based) rankings. JJ Arrginton for instance, was not rated very highly, but then people thought because he was going to "get the rock" in ARI he was a good pick.. Same thing with Brandon Jackon. Before the draft everyone knew he was borderline NFL material, then he went to GB, who had no RBs and people thought he was the #3 or #4 overall rookie.
Pre-draft rankings are based on talent. Post draft are clouded too much by situation. Michael Bennett also comes to mind, as many FF draftniks had him as the #1 RB when he went to MIN, but prior to the draft he was considered a very raw prospect.
Again, rankings BEFORE the draft IMO are MORE ACCURATE than those afterward. And I think all your examples proved it.
Nature vs Nuture... same debate right here. The case can be made for either side. However, I did a quick 5 minute search on the 2001 NFL pre-draft RB rankings:
http://www.nfldraftcountdown.com/archive/2...01rankings.html
Besides LT, Rudi Johnson has to be the 2nd best RB out of that class... yet he was ranked 8th. (An argument can be made for McAllister too, yes). For that list, Bennett was ranked #1... Now if my memory serves me correctly, LT was the consensus top RB at the draft, but even so, he wasn't touted as the second coming as he turned out to be... Being in WI, there was a LOT of hype about Bennett. I was really bumed to see him go to MIN because now I had to "hate" him... but he was regarded as the second best back the the draft. He was considered a raw prospect, yes, but top 2 or 3 nonetheless with plenty of upside. He was definately not upgraded just because he was a starter right away in MIN...
Okay, so that's too long ago huh? How about last year:
PREdraft
http://www.cstv.com/sports/m-footbl/stories/041807aaw.html
I'll save you the trouble:
1- AP
2- Lynch
3- Leonard
4- Pittman (cut by his drafted team)
5- Hunt
6- Irons
7- Booker
8- Bush
9- Wynn
10- B.Jackson
So you hold the 1.03, 1.04 pick in your draft, you really want a RB... and you take Leonard? Pittman?? You'd be stuck with your RB being a backup or flat out cut. Why not take a gamble and try to grab B. Jackson... selected 2nd round with no one in front of him starting... I'd rather have that than someone who's slated to be a backup from the start. That didn't pan out, but at least I would have had a chance at success than being doomed from the get go (and yes I'm aware Leonard started for Jackson while he was hurt, but he didn't do that well...)
POSTdraft (going off of SI.com,
http://sportsillustrated.cnn.com/2007/fant...ngs/index.html)
1. Lynch- My guess is he's #1 because no one is starting in front of him, he's starter from day 1
2. AP- He's really good, but before the draft injury was a concern and not to mention the LOCATION he was drafted in had Chester Taylor starting
3. B. Jackson- He's starting from the get-go too
4. Chris Henry- He wasn't even on that list of top 10... but given Travis Henry left TEN, and White proved nothing his rookie year, Chris Henry was a back who had a good opportunity
5. Booker- A backup
6. Leonard- A backup to who many thought would be the #1 RB that season
7. Selvin Young- Not on that top 10 list, but in DEN so DEN RBs get automatically upgraded.
8-10 not even worth mentioning... On this SI.com rankings list Young was at 64 overall among RBs, I highly doubt teams will be drafting 7 RBs each...
So how many of those were correct with the PREdraft rankings?
I think the question that really needs to be asked is- how many of you guys actually perform a rookie draft BEFORE the NFL draft????????

... anyone?

Okay, so no one, so why even have these discussions pre-draft? Keep your pants on, and wait until after the draft... yes, predraft is based off of pure talent, but what if that pure talent has to SIT behind an awesome starter... then he's no longer the best RB in that class that year...
