Problem: Research for tank casualties in Normandy from 6 June to 10 July 1944 conducted by the British No. 2 Operations research concluded, that from a sample of 40 Sherman tanks, 33 tanks burned (82 percent) and 7 tanks remained unburned following an average of 1.89 penetrations. In comparison, from a sample of 5 Panzer IVs, 4 tanks burned (80 percent) and 1 tank remained unburned, following an average of 1.5 penetrations. The Panther tank burned 14 times (63 percent) from a sample of 22 tanks and following 3.24 penetrations, while the Tiger burned 4 times (80 percent) out of a sample of 5 tanks following 3.25 penetrations. John Buckley, using a case study of the British 8th Armoured Brigade (United Kingdom) and 29th Armoured Brigade (United Kingdom), found that of their 166 Shermans knocked out in combat during the Normandy campaign, 94 (56.6 percent) burned out. Buckley also notes that an American survey carried out concluded that 65% of tanks burned out after being penetrated. United States Army research proved that the major reason for this was the stowage of main gun ammunition in the vulnerable sponsons above the tracks. A U.S. Army study in 1945 concluded that only 10-15 percent of wet stowage Shermans burned when penetrated, compared to 60-80 percent of the older dry-stowage Shermans.

Problem: Looking for their first road victory of the season, the Bills traveled to Soldier Field to take on the second of their four NFC North rivals, the Chicago Bears, in Dick Jauron's first return to Chicago since being fired at the end of the 2003 Chicago Bears season. From the start, Buffalo was in trouble, as Robbie Gould kicked two FGs in the first quarter-- a 42-yarder and a 43-yarder. Then, in the second quarter, three straight scores came from the Bears-- an 8-yard pass from Rex Grossman to Bernard Berrian, a 1-yard run from Cedric Benson and a 15-yard pass from Grossman to Rashied Davis-- that put the Bills in a deep hole. In the third quarter, Gould put up another FG for Chicago, this time from 32 yards out, while in the fourth quarter, Gould would kick a 41-yard FG and Benson would get another 1-yard run. The Bills would finally get on the board, as J. P. Losman completed a 5-yard strike to Lee Evans, ending the Bears' 11-quarter streak of not allowing their opponents to score a TD going back to the fourth quarter of the Bears' 34-7 victory against the Detroit Lions in Week 2, but the damage was already done, as the loss dropped the Bills to 2-3.

Problem: For the third consecutive season the Patriots faced Andrew Luck and the Colts, with Luck looking to beat the Patriots for the first time in his career. The Colts overcame their inability to finish off drives like in years past, marching on a 13-play, 89-yard drive, draining 7:44 off the clock and scoring a 5-yard touchdown pass from Luck to Donte Moncrief for an early 7-0 lead. The Patriots answered, going 80 yards in 10 plays, with Brady finding Edelman for a 12-yard touchdown pass, tying the game 7-7. Afte a Colts three-and-out, the Patriots drove to Colts 22 and Gostkowski made a 39-yard field goal. After another Colts punt, Mike Adams intercepted Brady and returned it 14 yards for a touchdown. The Colts bizarrely tried an onside kick, but the Patriots recovered at their own 35. It took just four plays to score, with Blount busting off a 38-yard touchdown run, giving the Patriots a 17-14 lead early in the second quarter. The Colts countered yet again, though. Stringing together a 10 play, 80-yard drive, scoring on 3-yard touchdown pass from Luck to T. Y. Hilton, giving the Colts the lead again 21-17. The Patriots drove to the Colts 7 and Brady hit Chandler for a 7-yard touchdown, but the play was nullified on a pass interference call on Chandler. Gostkowski kicked a 35-yard field goal on the next play, giving the Colts a 21-20 lead at halftime. The Patriots took the first drive of the second half, driving 80 yards in 7 plays, scoring on Brady's 25-yard touchdown pass to Gronkowski, giving the Patriots the lead again 27-21. Four possessions later, the Colts reached the Patriots 37 and attempted a trick play on fourth down where nine players lined up wide right, while Griff Whalen lined up at center and Colt Anderson lined up as a quarterback, hoping to catch the Patriots offsides; the play failed and Anderson was sacked for a one-yard loss, leading a befuddled Al Michaels in the NBC Sports booth to mutter, "What in the world?" The Patriots declined an illegal formation penalty on the play. Taking over at the Colts 35, the Patriots needed just 6 plays, scoring on an 11-yard screen pass from Brady to Blount, increasing their lead to 34-21 a few plays into the fourth quarter. Several possessions later, the Colts drove to the Patriots 38, but turned the ball over on downs again. However, the Colts forced a quick three-and-out, and raced 85 yard in 8 plays, scoring on Luck's 18-yard touchdown pass to Whalen, with a missed extra point from Adam Vinatieri, keeping the score 34-27 with just 1:19 left. Gronkowski recovered the Colts onside kick attempt and Brady took two knees to end the game. This was the Patriots sixth straight win in the series. The game lead tied or changed five times by halfway through the third quarter.
