A free spirit who marched to his own drumbeat, Pat Tillman was drafted by the Arizona Cardinals in 1998 after excelling at linebacker at Arizona State University. He moved to safety in the NFL, and in 2000, he recorded 155 tackles.
At one point during his pro career, he turned down a big-money contract offer from another team out of loyalty to the Cardinals. After the 9/11 attacks on the United States, Tillman passed on the NFL and signed up with the Army Rangers to serve in the invasion of Iraq.
Tillman was subsequently killed in a controversial friendly-fire incident at the age of 27. His number has been retired by both the Cardinals and ASU.
