See, I think chucking and ball hogging are different. I mean, I hate a black hole as much as the next guy, but a block hole is miles better than a chucker. A chucker, in my mind at least, throws up jumpers that don't have a high success rate. I actually think a chucker could be defined as an inefficient black hole. A guy who not only hogs the ball and takes a lot of shots, but makes matters worse by missing those shots the majority of the time.
That might just be my definition though.
I see your point but i generally view them as going hand in hand. guys who are black holes tend to chuck up terrible shots and vice versa
