I hadn't been to the Packer blog at JSOnline for quite some time. Read some older posts and stumbled across this -
Ryan Grant should benefit from having Korey Hall around. With Hall in the lineup, Grant averaged 4.2 yards per carry and had a DVOA of -3.2%; without him, Grant averaged 2.9 yards per carry with a DVOA of -26.9%. If I was Korey Hall and I read that statistic, dinner would be on Ryan Grant every night for the next six months.
This is from "Football's Outsiders Almanac". I know there are quite a few people calling for Quinn Johnson to start, but maybe the answer to fullback was on the existing roster. Don't forget, Johnson, like Hall, was a converted linebacker.
On the other hand, what does this say about John Kuhn?
For those wondering what DVOA is, this is how they describe their stat
Our primary statistic at Football Outsiders is DVOA -- Defense-adjusted Value Over Average. It's a simple idea: We take every play from the NFL season and compare it to the league average on the same play, after adjusting for down, distance, game situation, and the quality of the opponent.
So if I'm interpreting this right, Grant runs plays 3.2% less effective than the average play in the NFL, which really isn't that much. But, the -26.9%, well let's just say that's not so good.
