That's nothing but a trick to get fighters come rather than fight scared all trainers do it, and dumb sparring partners get sent home fast. You better take your time sparring with PAC or get your ass beat.
Nothing new. There is a legend of a journeyman heavyweight named Mel Turnbow, who flattened his boss Floyd Patterson after being given a similar incentive.
Its meaningless, and has anyone chimed into that other thread that has floated around for days here??? Roach makes Pacquia's spar partners wear 16oz gloves, while Pacquiao wears smaller ones.:hey
It would be very bad but hilarious at the same time if it backfired and had some egotistical puncher come in and damage Pac for the challenge and disrupt his training.
