History Lessons

This puzzle had a large sign. The more we studied it, the less we liked it.

 

Bears 26 Tigers 10

Indians 14 Giants  9

Hawks 108 Wolverines 97

Rams 3 Paladins 1

 

+7

 

We tried multiplication, we tried division, we tried figuring out what the sports were, we ignored our history. "Four Score and seven years ago..." So the answer was 87.
