i think theyll be happy taking the risk, if he loses he loses to Martinez who is rated as the 3rd best P4P boxer at the minute and destroyed Williams and Dzinziruk recently. Theres no shame and he has a shot at lasting longer than Williams who is classed as a world level boxer. On a very longshot he wins (and many will say Martinz was a hype job) and is elevated massively in the eyes of the world, will be no 1 in the division and can take on whoever next.
Getting destroyed by Sergio puts him no worse off than Paul Williams. If Barker can put on a good showing then his stock will go up. If he could win, it would a HUGE upset.
