Drew Bledsoe could be a blessing or a curse for second-year coach Gregg Williams. While Bledsoe gives Williams the quarterback who could propel this three-win team to the playoffs, the expectations may be higher than Williams and this young team can deliver. A seven-win season would be respectable for a franchise on the rebound, but will fans and owner Ralph Williams accept less?

After all, except for run-stopping tackle Pat Williams, the Bills don't have proven, stud linemen like they did in their Super Bowl days. End Aaron Schobel and tackle Ron Edwards have a chance to step into those roles but they aren't the only linemen who have to come through this season. Schobel played well last year. How weak were the Bills up front last year. Cornerback Antoine Winfield was their leading tackler.

Williams' second biggest chore is pulling the offensive line together into a consistent unit. Former Bills quarterback Rob Johnson held onto the ball too long, leading to a 46-sack season for the Bills line, 10th worst in the league. Except for guards Jerry Ostroski and veteran leader Ruben Brown, the Bills will go young on the offensive line. Rookie Mike Williams, barring a lengthy holdout, will add power to the right side of the line. Newcomer Trey Teague needs to handle John Fina's old spot at left tackle while Jonas Jennings takes over at center. Protecting Bledsoe will be the key.

Complicating matters is the schedule. The Bills could be improved but it will be tough to prove in the win-loss column. The Bills have one of the league's hardest schedule and a very difficult starting five that includes the Jets, Vikings, Broncos, Bears and Raiders.

Man in the spotlight
All eyes will be on Bledsoe. After signing what he thought was a lifetime contract (10 years, $103 million), his Patriots career crashed last year. He suffered a serious hit that opened an internal artery and made way for Tom Brady's Super Bowl run. Bledsoe threw only 66 regular-season passes and needed a Hail Mary trade on the second day of the draft to get a starting job in Buffalo. In many ways, he comes to a team that has bigger, more explosive receivers who may better fit his style -- Eric Moulds, Peerless Price and rookie Josh Reed. Bledsoe also has the support of quarterback-friendly offensive coordinator Kevin Gilbride, who will try to spread the field to take advantage of Bledsoe's powerful arm.

Key position battle
Williams has plenty of options at left tackle, but he has to make the right decision. For awhile, Williams thought about using Jennings at left tackle and Teague at center, but he switched things around in the minicamp. Whether it's Teague, the former Broncos starter, or Jennings, Bledsoe's blindside has to be safe. Asking Williams to be a starting left tackle as a rookie might be a lot to ask, but it's not out of the question for the future.

Injury update
The Bills don't have too many injury issues. Backup quarterback Alex Van Pelt is coming off successful shoulder surgery. Defensive tackle Pat Williams had minor ankle surgery and is fine. Guard Jerry Ostroski is coming off a minor knee scope that shouldn't give him problems. The biggest concern is fourth wide receiver Reggie Germany, who many not be ready until the first couple weeks of camp coming off a scoped knee.

Rookie report
Williams is this year's Leonard Davis, but the Bills decided to use him at the more visible right tackle spot instead of guard. He should open big holes for starting halfback Travis Henry to run right. The sleepers in this draft could be defensive linemen Ryan Denny (an end) and Justin Bannan (a tackle). Of course, the defensive line of the Bills is in such flux that a third-stringer could become a starter in a week.
