Wiseman would be a good choice. He would definitely fit the "Badass" image that hammer wants to portray. PDW fits that image, but I don't think he'll leave Storm. I still stick with my new pick that Robert Smith should switch over to Hammer.
I'm going to throw this name out because his actions recently: Randy Pedersen. Yes, I know what your thinking, why him? Like him or not, this guy plays with a lot of intensity, and he wears his emotions on his sleave. In the Tournament of Champions, Randy got pissed at the fan that distracted him on his last shot. He doesn't hold back on his comments, and he'll tell fans off (i.e. John McEnroe). I'm not saying this guy is my favorite player. This guy is a walking controversey, and if Hammer wants a badass, Randy maybe the one.
