I felt slightly bad about rooting for the higher-budget, bigger-bully Red Sox, an involuntary reflex reflecting all the years of counting on them (faute de mieux) to stop the Yankees. I also wanted the thing to end already, so I wouldn't have to keep on staying up late.
If you think the World Series outcome was inevitable, even after 8 innings of Game 4, think back to game 4 of the 2004 ALCS. It's difficult to draw any distinction between the Yankees' degree of dominance (and seeming inevitability) through that point in 2004, and that for the Red Sox this time around. E.g., the Yankees in 2004 had outscored the Red Sox by 36-19 through the 8th inning of game 4, versus 29-10 for the Sox this time around.
Only, Rivera blew it and Papelbon didn't.
