Small's balls....!
I don't seem to find any mention of the plot hole concerning the Babe Ruth ball. Clearly he and step-dad had another baseball that they used to play catch. I highly doubt they were playing catch with the Babe Ruth ball. When Denis Leary comes in the kitchen to put a steak on the kids' black eye, he clearly puts his ball and glove on the kitchen counter top. So why didn't Smalls go home and get THAT ball? Just wondering.
I am 55 and I love this movie. This is a movie for adults who remember this bygone era.
