That's not exactly what I'd call a thorough personnel evaluation.
Signing LeGarrette Blount is buying high on a straight ahead plodder without much lateral wiggle. He reminds me a lot of Peyton Hilis, actually. Similar skill sets. You guys really must not be watching the same game I'm watching, where Blount is feasting on wide open running lanes where he isn't even being touched until he gets to the second level. A back like him is always going to thrive when he's given the chance to bully corners and safeties once he has a head of steam. The challenge is getting him there.
If we signed him he'd find a much different kind of sledding trying to dodge tacklers in the backfield. Lots of carries where he takes a few tentative steps toward the line, tries a pitiful juke, and then he goes down timidly. Meanwhile Dolphins fans are mystified he isn't galloping through the secondary.
The story of this game is the New England Patriot offensive line. It's maybe the most underrated unit in the league, even though it features multiple high round picks. With Brady and Belichick around there aren't too many column inches to go around, I guess.
