Atwater (b. 1966) played pro football from 1989 to 1999 for the Broncos and Jets. He had 24 interceptions for 408 yards in his career. He won the Super Bowl twice with the Broncos (1997 and 1998) and was elected to the Pro Football Hall of Fame in 2020.
I mailed to Atwater on January 26 and got the card back on March 18, for a 51-day TAT.
