a new personal best, throwing for four touchdowns in a 49–26 victory. In Week 16, against the playoff-bound Arizona Cardinals, Cassel led the Patriots to a 47–7 blowout win through snow, sleet, and rain in the Patriots' last regular-season home game of 2008. Cassel, playing in snow for the first time ever, nevertheless completed 20 of 36 passes for 345 yards, three touchdowns, and no interceptions, while helping the Patriots remain in the hunt for the AFC East title. In a role reversal, Matt Leinart entered the game as the Cardinals' backup quarterback when Kurt Warner was pulled from the game with the Cardinals trailing 44–0; Leinart completed 6 of 14 passes, for 138 yards, a touchdown, and an interception. In Week 17, Cassel led the Patriots to their fourth consecutive win, 13–0 over the Buffalo Bills in a game marked by winds so severe that they bent the goalposts both before and during the game. Cassel completed 6 passes out of just 8 attempts, the third-lowest attempt total in franchise history (the second-lowest being the 5 attempts of the 1982 Snowplow Game and the lowest being the 3 attempts of their 2021 Week 13 game against the Buffalo Bills). Cassel finished the game with 78 yards; his most notable play, however, was a quick kick punt on third down in the fourth quarter; with the wind at his back, Cassel's kick landed inside the 20, and then rolled towards the Bills' end zone before it was downed, stranding the Bills at their own 2-yard line, struggling against the wind, down two scores with five minutes remaining. On January 4, 2009, ESPN's Chris Mortensen reported that the Patriots would franchise tag Cassel. The Patriots made it official on February 5, 2009, the first day of the 2009 franchise period, and Cassel agreed to the tender two days later. By the end of the 2008 season, Cassel had become the first quarterback in NFL history to record at least 10 wins, 325 completions, a 63% completion mark, 3,600 passing yards, 20 touchdown passes, 11 or fewer interceptions, and 250 rushing yards in a single season. As of 2017, only two other quarterbacks have accomplished the feat, Russell Wilson (twice) and Aaron Rodgers (five times).
