Variations can be confusing. They're most popular in baseball and haven't caught on the same in football and basketball.
You gotta research which ones are the variations and the subtle differences. The Hurts one is easier because he's wearing different jerseys but sometimes it's as little as a slightly different pose or the front has the regular team logo or helmet.
Any idea off the top of your head if the one with his white or green jersey is the more valuable? So much shyt to know..
