There is nothing to prove it but hearsay from neighbors and cops but I'm pretty sure Josh and Stephon's falling out started when Josh supposedly knocked up a local bartender cheating on his long time girlfriend at the time. Say what you want about Diggs being a diva but the man has strong fuckin values and I think it totally disappointed him enough to end their very close friendship. Again nothing to prove this and I'm just going on what I've heard in the Orchard Park community.
