Chris Mack can tell Edmond Sumner a few things about knee injuries, namely, “You ain’t seen nothin’, boss.’’
Mack is a master of the knee surgery. He could be a case study for blooming orthopedic surgeons. His knees look like a railroad terminus, four inches of track-stitching, from just below the knees to just above them. There’s the scar from the first torn ACL, on his left knee, and the scar from the second torn ACL, on his right. He blew them out within seven months of one another.
