Figure This!

Since each game can only have one winner, the four winners picked by each sportswriter are not playing each other. One way to organize the rest of the information is to make a chart like the one shown below.

There are eight teams involved in the four games. Each X in the chart shows a matchup that can be ruled out using Perimeter's picks. What match-ups can be ruled out using Exponent's picks?

Pacer
