Trying to figure out how to loop this and make it my background. I don't watch a lot of football but noticed the predator look is apparently in style these days. Wondered when it would happen.

It's happened a bunch before. 

In the NFL, your hair is technically a part of your uniform. I've seen many a wideout get their hair pulled. 

Although now that I think about it, I don't know why you can tackle by the hair without it being called for a horsecollar tackle. 

Usually you only see defensive players with really long hair, since they're the ones doing the tackling they don't need to worry as much about being tackled by their hair. But it does happen. Troy Polamalu was tackled by his hair running an interception back one time. 

He also has his hair insured now, or something.
