Maybe somewhere in bloggoland someone has already discovered this, but it happened to me and I'm ticked.
Opened up a discounted blaster of 2008 Upper Deck Baseball Heroes. 9 packs in a blaster, 5 cards per pack.
Not including the long worn out Yankee Stadium Legacy cards randomly included, every single pack had either a Yankee or Red Sox card in it. EVERY SINGLE PACK!
So I went to teamsets4u.com to see how many team cards there were and wouldn't you know it those two teams about triple the amount of cards the other teams have.
19 cards for the Red Sox and 19 cards for the Yankees. The other teams average about 6. And thats just base cards.
I swear I'm so sick of Boston and New York.
