For me it basically means that if your in the champs backyard & your doing very little, it'll be very hard to take the championship.

In regards to Dirrell/ Froch there were rounds where neither guy did anything. In that situation it can sometimes go to the known commodity.

I'm not saying its right, but a hometown crowd can sway those close rounds towards the champ & make it very difficult for the challenger to take the title.

Like in other sports sometime the ref seems biased or its a home or country game & calls go against the other team

It just means you need to bring your A-game to walk away with the win, leave no doubts!
