If Allen won't sign a long-term deal then trading him becomes the best option. As trades go from this position, this one isn't horrible. Lito Sheppard is a very good corner, and although he's a veteran, he isn't old...he'll be 27 in April. The #19 along with your current #5 could be used to get 2 offensive linemen or an OT & a WR. This would be huge. Then the only question is can the Chiefs get a viable DE in the 2nd round, or in free agency.
