He committed an illegal tackle that twisted another athlete’s body the wrong way while running and got him seriously injured (in fact, thus far has ended his career as a starter in the NFL). Launching yourself like that and spinning another player around leads to injury, especially as he likely outweighs the opposing player. If that’s not the definition of dirty, I don’t know what is, but to each his own.
Personally, I dislike Devin White because his “poor tackling form” started us going down the worst timeline possible. We missed the playoffs that year, then Sean leaves, and now we’re stuck the the substitute teacher.
