I've called Chicago Bears 2nd round rookie Eddie Goldman the key to their defensive line. I'm not saying he's their best d-lineman, but his ability to win a starting job, or at the very least, become a major factor in the rotation, will go a long way into stabilizing the unit.
Goldman has had some time with the ones at nose tackle during training camp, but he opened up on the first unofficial depth chart listed as a backup behind Jeremiah Ratliff. While Ratliff is quite capable of playing the nose, I'd like to see him kick out to defensive end on occasion, because that will be easier on his soon to be 34 year old body.
