Last week, Raiders quarterback Derek Carr signed a five-year contract extension worth $125 million, with $70 million fully guaranteed. The Carr contract resembles that of Andrew Luck, who signed an extension with the Colts in 2016 worth $140 million. Luck received $87 million guaranteed. All of these quarterbacks owe a huge thank you to Ravens quarterback, Joe Flacco. Before Flacco signed a massive six-year $120 million contract extension in 2013, Drew Brees was the quarterback who carried the NFLs largest contract at the position.
