Melvin Guillard. He's 1-4 in his past five, lost three of those fights by being finished in the first round, is riding a two-fight losing streak, looked flat in his last fight, missed weight for one of his losses, and his lone win came in boring fashion.
Shane Carwin hasn't competed in almost two years, has lost two in a row, and is now 38 years old.
Joey Beltran is 1-3 with one NC in his last five, and he just tested positive for steroids in his last fight.
Thiago Silva officially hasn't won a fight in three and a half years.
Any others that probably have it coming soon?
