The claim that Aaron Donald is the only DT to win Defensive Rookie of the Year since 2000 is false. Ndamukong Suh also won this award in 2010. The correct answer is (B) False.
The statement that Aaron Donald is the only defensive tackle (DT) to win the Defensive Rookie of the Year since 2000 is false. While Aaron Donald did win this award for the 2014 NFL season, Ndamukong Suh also won the Defensive Rookie of the Year award as a defensive tackle in 2010. The AP Defensive Rookie of the Year is given annually by the Associated Press to the top rookie defensive player in the NFL, and multiple defensive tackles besides Donald have been recipients since 2000.
Therefore, the correct answer to the question is (B) False. Aaron Donald is not the only DT to achieve this since 2000; Ndamukong Suh also received the accolade.
