I want a big time sack guy as much as anyone, but Hardy sounds like a guy making decisions that bring a lot of drama in his life.
If his ex was a party girl and an admitted narcotics user, seems very plausible that he knew about it and was indifferent to it. That's best case scenario. It doesn't seem like it was a situation where she had this secret addiction and he knew nothing about it. He wasn't married to her. Didn't have kids with her. If he wasn't okay with it in his life, he could have just ended that relationship. Add in reports of him keeping a mini arsenal. I don't know...there are some large warning signs with this guy.
It would have to be a super team-friendly contract. I don't see how you could give a big contract to Hardy while playing hardball with Dez.
