2010 was a very competitive season for the Canadian Football League, as seven of the eight teams were bunched together in the standings, with the exception of the Winnipeg Blue Bombers who finished with a lowly 4-14 record. The other seven teams ranged between 7 and 13 wins. Calgary (13-5) won comfortably by three games over second place Saskatchewan (10-8) in the Western Division, while Montreal (12-6) would also take the Eastern Division by three games over second place Hamilton (9-9) and Toronto (9-9). In the first round of the playoffs, the Toronto Argonauts would take care of the Hamilton Tiger-Cats 16-13, while the Saskatchewan Roughriders would need to go to double overtime to defeat the BC Lions 41-38. In the Division Finals, it was the Montreal Alouettes rolling over Toronto 48-17, while the Roughriders would upset the Calgary Stampeders 20-16, setting up the match-up for the 98th Grey Cup. In a rematch of the 97th Grey Cup, the Alouettes defeated the Roughriders for the second year in a row, 21–18, becoming the first team in 13 years to win back-to-back Grey Cups. The game was played on November 28, 2010, at Commonwealth Stadium in Edmonton, Alberta. This marked the first time that the Grey Cup was played in the province of Alberta in two straight years. (Calgary hosted the previous Grey Cup game.) The Alouettes opened up a 7-0 lead 5:39 into the first quarter on a three-yard run by Cobourne as the Riders were pinned deep for most of the opening 15 minutes. Then Duval missed a 31-yard field goal, wide right, scoring a single point to make it 8-0 Montreal at 11:14. The momentum seemed to shift from that point on. A pass interference call on Chip Cox in the Alouettes' end zone gave Saskatchewan a first-and-goal on the Montreal 1-yard line, and Wes Cates scored a touchdown to end the first quarter, with the Alouettes leading 8-7. In the second quarter, Warren Kean kicked a 27-yard field goal to put the Roughriders up 10-8 at 3:10 into the second quarter. The Roughriders added to the score with a punt single by Eddie Johnson with a minute to go in the second quarter, and ended the first half with an 11-8 lead. Jerrell Freeman had an excellent half on defense for the Roughriders with three tackles, a quarterback sack, and two pass knockdowns. One of the key plays of the game happened with 11:06 left in the third quarter, when Marc Trestman gambled on a 3rd-and-2 with a fake
punt on the Montreal 41-yard line. The direct snap went to receiver Eric Deslauriers, who ran ten yards for the first down, and that play helped set up a 22-yard Damon Duval field goal to tie the game 11–11 with 5:35 left in the third quarter. With 13:23 remaining in the fourth quarter, Damon Duval kicked a 42-yard field goal to put the Alouettes up 14-11. On a 2nd-and-5 play scrimmaging from the Saskatchewan 52-yard line with 9:37 left in the fourth quarter, Byron Bullock appeared to intercept an Anthony Calvillo to Ben Cahoon pass attempt. However, Bullock committed pass interference on Ben Cahoon, which nullified the interception, and resulted in a ten-yard
Saskatchewan penalty and a first down for the Alouettes. Later during that same Alouettes' drive, on a 2nd-and-7 from the Saskatchewan 40-yard line, Calvillo successfully threw to Jamel Richardson who was in tight coverage by Roughriders' cornerback Omarr Morgan on the Saskatchewan 2-yard line. Avon Coubourne scored on a 2-yard touchdown run to put the Alouettes up 21-11 with 7:46 left in the 4th quarter.  With 1:07 left in the game and the Roughriders 1st-and-15 at their own 25-yard line, Darian Durant broke out of what looked like a sure sack by Diamond Ferri at the Roughriders' 18-yard line. Durant ran left along the Roughriders' 19-yard line, escaped a diving tackle (by Alouettes' defensive end Jermaine McElveen), and then Durant then threw the ball downfield toward the left sideline, but was intercepted by Alouettes' defensive back Billy Parker at the Roughriders' 38-yard line with 56 seconds left in the game. The Alouettes kept the ball on offense for the remainder of the game to win 21-18. Montreal wide receiver Jamel Richardson, who made eight catches and had a game-high 109 yards, was named Grey Cup MVP. Saskatchewan defensive lineman Keith Shologan was named the Grey Cup's Most
Valuable Canadian.
