because Bob thinks boxing fans are idiots and only buy PPVs to watch the main events plus he's a dirty lying cheapskate who despite being 80+ years old and filthy rich would fight you for a dollar lying on the street
TR undercards for Pac/Bradley 2 may not be up there in name but they are good fights imo. They could do better though..
arum is jewish which in turn makes him want to save every penny he can. Cheap undercards=pennies saved. it's not science here people.
Because arum says people don't care about it. I do though as do many hardcore fans. I fell asleep after Vargas fight but luckily woke up in time for PAC brad
