who was tom brady backup when he got hurt
Matt Cassel Cassel became the Patriots' starting quarterback after Week 1 of the 2008 season after then reigning NFL MVP Tom Brady suffered a season-ending knee injury. According to ESPN research, he is the only known quarterback in NFL history to start an NFL game at quarterback without ever starting as a quarterback in college. In February 2009, the Patriots used their franchise tag on Cassel, extending him a one-year contract worth over $14 million, the largest one-year contract for an offensive player in NFL history.[1][2] Later that offseason, the Patriots made a trade which sent Cassel to the Kansas City Chiefs,[3] who signed him to a 6-year, $62.7 million contract in July 2009. In 2010, Cassel led the Chiefs to their first AFC West divisional championship in seven years, and earned a Pro Bowl berth in the process. On April 4, 2018, he agreed to terms with the Detroit Lions, reuniting with Matt Patricia from their years with the Patriots.
