Jens is still a huge threat in the lw division for the ufc. Just because he was going to boxing and back to mma doesn't mean he's still not dangerous. I don't know about him being demolished by B.J. especially since he already holds a win over him at UFC 35 where it went all five rounds in a good fight. He's a top dog, don't make no mistake about it. There is a lot of good competition though for him like you said.
