I have no idea how this will work out for Dallas, but the last time I saw Collins play for the Bengals, he was pretty awful. He was stiff, slow, immobile, and his footwork was horrible. he had significant back problems.. Since then he had a knee injury and surgery. I have no idea what he looks like a year later but unless he found a miracle cure for all his ailments, I cannot believe he has much left to give.
Still, I am open minded. But then this raises the questions. If the Cowboys had doubts about their two young backups, why did the bring Waletzko back from IR and cut the LB, Evans?
