1999-00 Topps Alonzo Mourning #10

Mourning during his peak with the Miami Heat, the year he won Defensive Player of the Year for the second time. He anchored Pat Rileys defensive system with 3.7 blocks per game while averaging 21.7 points. His warrior mentality and finger-wagging rejections made him the most feared rim protector of his era.
