some interesting data about the fighters:
Cannetti 38 years old, 2 and a half years lay off (got caught by USADA) is fighting Ho kang, 8 years younger, 3''taller with +4'' reach. Ho kang 3 years lay off (militar service)
Aldritch is 3 years younger, 5'' taller with +7'' reach (massive difference) is fighting Taylor.
Alex White was born in Missouri (local) and is 2 years younger than Krause who is 2'' taller with +2''reach (Krause is located in Missouri too but was born in Virginia)
Cummings is 1 year younger, 3'' taller with +5''reach. Cummings was born in Texas but is located in Missouri so he will be the local against the brazilian Thiago Alves.
Michael Johnson drops from LW to FW (first time in his career right? at least in UFC), 2 years younger with +2'' reach, he is fighting Elkins.
Johnson was born in Missouri too, local factor.
