Danilovic
Alright, we'll stay away from value-judgement, although when you've got a documented rap sheet as long as Danilovic's, "surly" is almost a compliment. 
Yes, Blic is a reliable source. It's one of the high-circulation dailies in Serbia. Yes, it's a middle-market tabloid, but it doesn't invent stories. It's very similar to Britain's Daily Mail. Plus the case of Danilovic beating up referee Juras is well-documented in Serbian media as well as the resulting sanctions, both basketball-related and civic.
