In answering LA's question, I agree completely with Labatts outlook for round 2. If either Baas or Spencer are available, they'd be hard to pass on. The only 2 Centers who could start immediately, whether you needed them to or not. Baas can also start at Guard. Teague is in the last year of his contract, I believe.
Still, history shows you never know with the Bills. They were checking out DT Attaj Hawthorne of Wisconson. Could be a CB, with the Clements situation in mind.
