It's pretty obvious that if Tito loses, this is the end of the line. That being said, I think it might be a wake up call to Tito. He still has something left in the tank, I mean, his last four fights have gone the distance, against some great competition (Hamill, Griffin, Machida, and Evans) and in some of those fights he could have won. Ortiz has been lacking his old explosiveness in the cage, but he's still an excellent wrestler, so Ryan Bader won't be able to take him down at will, but not only that, Tito will be motivated. Tito isn't the type of guy to let Bader choose him as a "quick win," Ortiz will come out swinging, I promise. Ortiz has nothing to lose, Bader doesn't have that pressure or that motivation, Tito knows that if he doesn't win, his UFC career is over. Hell, I'm sure he's aware that he's lucky to even have the opportunity against Bader.
Yes, at this point in their careers, Bader is the better fighter. Bader is a, what, 3:1 favorite to win, so I'm aware that it's unlikely Tito will win, but I don't want to see him go out by getting knocked the fuck out.
