I'm not trying to knock sports but what 1 year old really cares about them?
Especially the jerseys?
I'm sorry but I think that a baby would be far happier with something they liked to play with like a ball, duck, bear, truck, doll, etc. Not that they really care much at that age about what their cake looks like anyway.
Maybe next time you should specify what they're paying for, say it will be $XX for a sheet cake with that drawn on it and then if it's not what they want they'll correct you and say "no I want it carved."
