Pruneda is 6'7" and 320 pounds. This story is creating a little buzz around the blogosphere but put me on record right now as saying Pruneda will have little to no impact and that the Chiefs are obviously really, really desperate for O-line help. Call it a hunch.
Carl, there is a reason why there has only been one other nonkicker to come out of Mexico. This is not baseball and Mexico is not Japan. The only reason I would give Pruneda any credence is because Grunhard is backing him.
