Yeah, for example, I think the Red Sox got really lucky in 2007. They never should have pitched Wakefield in game four, and they were somewhat fortunate that the offense showed up to the degree that it did the rest of the series. Also, after being given a 3-0 lead in game seven, Matsuzaka gave two of them back, and the Guardians were poised to tie the game in the seventh inning (I feel like Joel Skinner doesn't get enough grief for one of the biggest gaffes in postseason history). The way Beckett was pitching that postseason, if he's starting game seven, it's probably over at 3-0.
**I guess no one really talks about Skinner's mistake because of all the runs the Red Sox scored in the bottom of the seventh and the bottom of the eighth. But if the game is tied, it might have played out very differently.
