Ok, a couple of things here....
Jacare doesn't even have the MW strap for Strikeforce, he's not getting an immediate shot @ Anderson.... Added to the fact that they've already said they wouldn't fight one another.
Also, consider how Jacare has lost fights: Getting hit in the face, and being out-cardiod by a wrestler who didn't get submitted.
Jacare will lose to: Weidman, Lombard, Bisping, Belfort, and Okami. It's also entirely possible he would lose versus Wand, Cung Le, Sonnen, Stann, and Munoz.
He has potential to do well, and does offer some big challenges to many fighters in the division, but let's be real.... He is -zero- threat to the UFC strap right now.
