The guy is coming off two FOTY contenders, he's not going back to the prelims or "opening" a card for a while.
For Dos Anjos, Bocek and Njokuani are respectable wins but Varner and Guillard are much higher up in profile and rankings. Also Dos Anjos lost to Tibau who has lost every time he's taken a step up in competition (Khabib, Miller, Guillard, Stevenson, Griffin).
Lauzon may not be "winning more" than those guys but his losses are to top ten/five guys. Dos Anjos is still a year off from making the top ten in the division, Lauzon is arguably already there.
Let's be honest here. Joe beat a heartless Melvin, he is popular because he is a TUF alum who is entertaining. His overall resume is not more impressive then RDA or Tibau and realistically he shouldn't be ranked higher. He is more well known, has put on more memorable fights but his recent resume is not any better.
