"To see how ubiquitous and varied grieving via uniforms has become, look at the response to the April 2007 shootings at Virginia Tech. In the days immediately following the tragedy, Allen Iverson wore a sleeve patch; several MLB teams wore the VT logo on their caps or sleeves; some MLBers even wore VT caps (including Joe Saunders, baseball's only VT grad); several college football teams wore VT helmet logos for their spring scrimmages; and literally dozens of golfers, NASCAR drivers, and other athletes wore VT logos. When the fall sports season began, the Hokies themselves wore a black patch with an orange ribbon, and all other ACC football and basketball teams added small black memorial strips, although there was no uniformity regarding their placement: For football, they appeared primarily on the chest or shoulder; for basketball, here, there, and everywhere. It's like the entire sports world went into "Ich bin ein Hokie" mode."
