How can a god, that apparently loves everyone, allow this kind of thing to happen?

[John V]

I don't know about helping to find keys but I see a lot of professional footballers do the cross sign thing before a game. Are they not asking god to help their team win?

Maybe, or they could mean that glory should go to God either way.

And if they do win, do they attribute this to god?

Sometimes, but unless they say something like "God specifically told me to go with a draw on that touchdown play," such attribution would fall under the "general" category.
