It has been a harmonious existence since the late Bob Tisch agreed to purchase 50 percent of the Giants from the Mara Family in 1991. The partnership became admired throughout the NFL as the Tisch side handled the fiscal part of the business while the Mara side focused primarily on the football decisions.
When Bob Tisch and Wellington Mara died 20 days apart in 2005, their sons, Steve and John, assumed co-ownership. They have celebrated winning Super Bowls together, built a new stadium in the Meadowlands and watched as revenues skyrocketed.
But the Tisch and Mara families could find themselves at odds over whether to fire head coach Pat Shurmur and general manager Dave Gettleman.
