Carolina grooms a back, runs them into the ground, then drafts another one so they can get rid of the current one before they have to pay them the big bucks. This is Williams' last year in Carolina and they'll run him until his legs fall off imo.
While your opinion could certainly end up being right, I don't know if I agree with the premise on which you've based it.While Carolina has (over the length of Fox's coaching tenure) tended to focus on the run & have had a tendency to rely on more than 1 RB, I don't see Fox as a coach who always:
grooms a back, runs them into the ground, then drafts another one so they can get rid of the current one before they have to pay them the big bucks.
Fox has coached the Panthers since 20022002-The lead RB was Lamar Smith with 209 carries/707 yards (11 games). 2nd RB was Dee Brown with 102/360. Smith was 32, and playing for his 4th NFL team. I'd hardly say they groomed Smith, or that Fox ran him into the ground with 209 carries. Furthermore, they weren't grooming Dee Brown either, since he wasn't even on the team in 2003.
2003-The lead RB was Stephen Davis, acquired in free agency. He had 318 carries for 1444 yards (14 games). 2nd RB was DeShaun Foster (drafted in the 2nd round), with 113/429. One could argue that Carolina was grooming Foster to be Davis' replacement, and that they were running Davis "into the ground" while grooming Foster. However, since Davis was a free agent who had experienced a good deal of success in the NFL, it's hard to argue that he was being run into the ground. Rather that he was being used as the main RB, which is what he was being paid as.
2004-This year doesn't really tell us much of anything. Davis and Foster got hurt, which led to Nick Goings being the lead RB.
2005-This year, Foster was the lead back with 205 carries for 879 yards. Davis was 2nd RB with 180/549. It's important to note, however, that Fox kept Davis as the starter with 11 starts to 5 for Foster. If you wanted to argue that Fox was "running Davis into the ground" this season, you could. I'm, however, more inclined to agree that this was a case of Fox being loyal to his veteran player(s), and sticking with them. Especially when you have the advantage of looking at other examples of him doing the same thing.
2006-Foster was the lead RB, with 227 carries for 897 yards. 2nd RB was Williams (drafted in the 1st round), with 121/501. This is the first true example of Carolina "grooming" a RB, with Foster having spent a few years as the 2nd RB to Davis, now assuming the RB1 mantle.
2007-Foster was the lead RB, with 247 carries for 876 yards. 2nd RB was Williams again, with 144/717. Despite Williams having a higher YPC, YPReception, and more TDs, Fox stuck with his veteran. Foster started all 16 games. However, Foster had only 272 touches, so he was hardly being "run into the ground."
2008-Williams was the lead RB, with 273/1515. Stewart (drafted in the 1st round) was the 2nd RB, with 184/836. Foster was allowed to leave in the off-season. Williams was "groomed" for the RB1 spot, but I'd hardly say that Foster was "run into the ground." He averaged 195 touches/year (170 carries & 25 rec) in his 5 years in Carolina, with a high of 272 touches. He was 28 when they let him leave, so it's not like they "used him up" until the hit the wall at 30. He just wasn't very good, and was out-performed by his back-up, Williams. It made no sense to keep him. This could be looked at as the beginning of the "grooming" of Stewart, but Williams with only 295 total touches, could hardly be described as a back being "run into the ground."
2009-Just using the numbers, Stewart was the lead RB, with 221 for 1133. Williams was the 2nd RB with 216/1117. However, Williams missed 3 games (weeks 15, 16, 17), and was hurt early in a 4th (week 14). During those 4 weeks, Stewart received 76 carries to Williams' 6. Prior to week 14, the carry split was Williams-200, Stewart-145, a 58%/42% split. Williams had a higher YPC and a higher YPReception average. For that reason, 2009 could still be looked at as part of the "grooming" of Stewart, but AGAIN, Williams wasn't being "run into the ground."
So we have 3 examples of RBs being "groomed" in Carolina, under Fox, but THERE ARE NO EXAMPLES OF FOX RUNNING A RB INTO THE GROUND. Lamar Smith was already an old RB when Fox got to Carolina. Stephen Davis was a 29 year old, 7 year veteran, FA who had already had almost 1400 carries in the NFL, when he got there. Fox didn't run him into the ground, he was already almost there. Foster wasn't run into the ground, he averaged less than 200 touches/season during his 5 year stint.
Furthermore, there isn't a single example of Carolina, under Fox, getting rid of a RB before they had to have to "pay them the big bucks." Lamar Smith and Stephen Davis were past their prime when they left and neither were demanded "big bucks." Foster wasn't as good as Williams, and he didn't get "big bucks" elsewhere.
So while it's possible that Williams is going to be on another team in 2011, it's not nearly the lock that you seem to believe it is, based on past history of Fox OR the Panthers.
