The player in each block needs to correspond with the teams or stat it lines up with on both the horizontal and vertical axis. So block in top left corner you need a player that played for both the A’s and Mets. The percentage is how many respondents used that player. You get a better score at the end if you use players more rarely selected. So Bassitt and Chapman are really good selections at 2% but Hampton and Alonso are not because 28% selected them.
