Sign Alexander
This quote from Houston says it all: "He's one of the top running backs in the league," Robinson said. "I thought last time when I played against LaDainian Tomlinson, I thought he was the best. But not now. Alexander is a big, fast running back."
I admit to being one of those who doubted Shawn Alexander was the right running back for Seattle. Forget that. Sign him and ride him to the playoffs.
