‘Left guard: This is among the Buffalo Bills’ biggest areas of concern right now. Veteran Bennie Anderson is the starter, but he was absolutely awful last season. The organization hasn’t shown a ton of faith in second-year man Duke Preston, but it wouldn’t be shocking if he won the job. The Bills’ best bets are Charles Spencer from Pittsburgh, Davin Joseph from Oklahoma and Deuce Lutui from USC in Rounds Two or Three.’
