Wecker graduated from Kansas State University in 2005, where she was named Big 12 Conference Player of the Year in 2005. In 2003, 2004, and 2005 she was named to the All-Big 12 First Team. She was also named to the All-District Second Team in 2004.
Wecker was drafted 4th overall by the San Antonio Silver Stars in the 1st round of the 2005 WNBA Draft. In her first game of her rookie year, she tore her ACL and was out the rest of the season. On February 19, 2006 during the WNBA offseason, Wecker joined Tony Parker and Steve Kerr in the NBA RadioShack Shooting stars contest. She helped achieve the NBA shooting stars record time of 25.1 seconds.
In 1992, she qualified for the finals of the National Football League's Punt, Pass, and Kick competition, representing the Kansas City Chiefs. Wecker competed on an equal basis with boys and finished second, but her success inspired the NFL to install separate competitions for boys and girls in subsequent years.
