If you don't like just looking at stats, then don't just list the stats; watch the plays and compare the schemes, defensive penetration, and all the other factors that contribute. Stewart ran out of i formations and pro sets far more often than Williams did, and was met in the backfield fewer times (and no, he didn't turn those into positive yards when he was)
Also Williams did have a couple of 11 yarders called back by penalties if you'll recall.
williams ran out of the i formation 9x, stewart 5.
williams ran out of the shotgun 2x, stewart 3.
williams had 1 positive run called back. it was officially a 15 yard run. tossing that into his list of runs doesn't make his overall performance look any better.
people keep bringing up scheme being a limitation for williams, but i already posted a breakdown of how the backs have performed in different formations...
• Who is the most effective on zone-read plays? Newton, who averages 5.8 yards per zone-read carry, DeAngelo Williams averages 5.0 yards on those plays, and Jonathan Stewart gains 4.0 yards.
• The statistics support using Stewart more often than Williams on traditional handoffs. Stewart averages 5.7 yards per carry on traditional handoffs, with Newton starting under center. Williams has 30 yards on 18 carries on that type of play, a 1.67-yard average.
and now the lack of a zone blocking scheme is being tossed around as an excuse for williams...but the zone blocking scheme wasn't introduced until 2007.
williams ran fine in 2006 without it.
stewart is running at less than 100% with the same suspect oline and scheme...yet williams can't outperform him.
there are factors that play into overall performance, but there is no doubt that williams is on the decline.
