Geeze I know what it literally means. Didn't know I had to ask so specifically. This was tweeted as if he did anything significant, like it adds to his Heisman run. Behind all the "lining up at multiple positions" tweet, he had like 3 tackles and a handful of yards. But gets credit for doing what a regular safety does (line up in the box, cover WR when spread out, cover slot on nickel coverages). This is the first time I've seen someone get credit for lining up at different positions without having to produce at each one. Gets credit for lining up at WR yet he has 3 catches on the season. It's cool, it'll all come to light.
