‘Spain’s signing is an important one because it likely means the Bills are out of the high-end offensive line free agent market. If you notice below, most of the high-profile offensive linemen no longer appear on the target list. Spain’s re-signing indicates a high level of confidence by the team in Spain’s ability at left guard and Cody Ford’s potential on the outside at right tackle. That doesn’t mean the Bills still won’t look to add on the offensive line, but a big time signing is probably less likely. Oh, but there’s still one target in the Top 10 that makes sense.’
