I'm not buying the region to region excuse. When someone says you got the 7, it means it counts on the break unless it's the valled 7 or specifed differently which is not the case here.
When someone says "you got the 7" it means just that. It's a money ball like the 9ball now and it doesnt have to be called, if it goes on the break it counts (unless specified otherwise, which in this case it was not). The player getting the weight has to shoot the 8 and 9 if the opoonent has made the 7 on a legal shot. If the 7 is made illegally or on a push it get's spotted just like the 9 would. If the person giving weight says called 7, the it wouldnt count on the break unless thyey called a pocked on the snap and it went in there.
I thought when Chris said OMG has the 7 ball it was perfectly clear.
