mmaweekly.com The depth of talent at lightweight has to be something attractive for Melendez. He's already faced Josh Thompson and Mitsuhiro Ishida and lost to both--there isn't much left for him in Strikeforce. But as we've seen with other Cesar Gracie fighters (Nick Diaz, Jake Shields, etc.) the UFC isn't the only option for these guys.
He'd be a great addition to the LW division, but I don't think he's a championship contender. Note that I said contender, so long as BJ is at 155 and interested in keeping in shape, no one is taking the belt from him.
