Let's look at the Panthers under Fox:2002 - 452/1586/11 rushing; Lamar Smith led with 208/737/7 (3.5 ypc); team was 7-92003 - 522/2091/9 rushing; Stephen Davis led with 318/1444/8 (4.5 ypc); team was 11-5 and lost in the Super Bowl2004 - 422/1582/10 rushing; Goings led with 217/821/6 (3.8 ypc); team was 7-9; team rushing attempts down because both Davis (#1 on depth chart) and Foster (#2) were hurt early, and combined for only 83 rushing attempts2005 - 487/1679/17 rushing; Foster led with 205/879/2 (4.3 ypc); team was 11-5 and lost in the NFC championship2006 - 423/1659/7 rushing; Foster led with 227/897/3 (4.0 ypc); team was 8-82007 - 451/1824/7 rushing; Foster led with 247/873/3 (3.5 ypc); team was 7-9; QB carousel definitely hurt running game productionI think Fox definitely prefers to run a lot, and the two seasons in which the team was successful were the two best seasons for his running game. So the desire and offensive philosophy are there IMO.As of now, here are the RBs on the Panthers besides Williams:- Labrandon Toefield - 13 carries last year in JAX, 163 career carries in 45 games- Goings - 30 years old, 0 carries last year and only 48 carries since 2004- Alex Haynes - 3 carries last year as a rookie in CAR- FB Brad Hoover - FB, turns 32 in November, only 12 carries last year and 44 carries since 2004Meanwhile, Williams had 144 carries last season and averaged 5.0 ypc. So the only threat to Williams' rushing attempts at this point is a rookie. Given Fox's past tendencies to favor the veteran RB over the younger RB (Davis over Foster, Foster over Williams), it seems unlikely that a rookie will unseat Williams as Fox's lead RB, unless the Panthers draft McFadden, Mendenhall, or Stewart, which seems unlikely.So IMO Williams is clearly the lead RB for the Panthers this season. Fox's lead RB has never had less than 205 carries, even though that often meant giving that many carries to RBs who were averaging 3.8 ypc or less. So it is safe to assume that he won't see fewer than 205 carries... but he could easily see more. Foster averaged 237 the past couple of seasons even though he gave up an average of 133 carries per season to Williams.How about the passing game? Williams has shown very good ability there, with 56/488/2 receiving (8.7 ypr) in 29 career games. Those other RBs on the roster right now combined for 13 catches last season... none seem to be a threat to replace Williams in a third down RB role.And that receiving production for Williams was with Foster getting 57/341/1 over the same span (the last two seasons). Between them, they had 113/829/3 in the past 2 seasons, so it is possible there could be 45-50 catches available for the lead RB.What does all of this mean? Assuming the Panthers do not draft one of the big 3 RBs, I think it is reasonably conservative to project Williams with 240 carries and 45 catches. At 4.4 ypc and 7.5 ypr, that is roughly 1400 total yards, and I'd expect 6+ TDs if he gets those touches. 1400/6 was good enough for RB12 last year (FBG scoring), but I think those are conservative numbers with upside... he could get more carries and his career ypc (4.6) and ypr (8.7) are higher.Williams = value unless the Panthers draft one of the big 3 rookie RBs.
