1. Worst second-half team: Vikings » It's the same story in a different week for the winless Vikings, who lost their third straight game after leading by a large margin in the first half. Minnesota has blown halftime leads of 10, 17 and now 20 points with its 23-20 collapse to the Lions on Sunday. The Vikings are 0-3 for the first time since 2002.
2. Worst offensive line: Bears » The issue for the first two weeks was Jay Cutler getting sacked 11 times. Week 3 saw running back Matt Forte gain a mere 2 yards on nine carries against the Packers. The common thread is Chicago's abysmal offensive line, which lacks the ability to protect the quarterback and open gaps.
3. Worst injury: Michael Vick?» A week after suffering a concussion in a 35-31 loss to the Falcons, Vick injured his non-throwing hand in the third quarter of a 29-16 loss to the Giants. If Vick is unable to go, will the Eagles turn to Mike Kafka or Vince Young, who has been battling a hamstring injury?
4. Best rookie performance: Torrey Smith » The second-round pick from Maryland made the most of his first start. His first three catches of his career went for touchdowns of 74, 41 and 18 yards. He finished with five catches for 152 yards.
5. Best statement win: Bills » Buffalo overcame a 21-0 second-quarter deficit and defeated the Patriots 34-31 to snap a 15-game losing streak to New England. The Bills are 3-0 after starting 0-8 in 2010. Quarterback Ryan Fitzpatrick (841 yards, nine TDs) has the Bills in position to end an 11-year playoff drought.
