Watt always wears a huge arm brace to begin with...maybe Gronk got roid rage and decided to try and murder White but Watt would NEVER do such a thing, he is pure class.... also he is squeaky clean of roids so no rage to worry about except for his normal farm man 200% nonstop motor on every play.
Also TJ Watt is not a dirty player at all, just a clever sexy beast...
