Several trains of thought on this issue:
1. Djokovic has a right to say, hey don't overlook me. His response was simple, forthright, and truthful. There was no arrogance attached.
2. Fed said the same thing and people didn't think one thing about it, so that implies a double standard.
3. Everyone who enters the tournament has a chance to win it, not just the Big 4. Oddsmakers are trying to make money. Pundits are trying to keep their jobs. Controversy sells. A sad but undeniable fact.
May the best man win and may the fans not have sour grapes about it.
