Buddy Ryan was always a polarizing figure during his time in the NFL. In 1989, after rumors circulated that Ryan had issued bounties as incentives to his players for hits on Dallas kicker Luis Zendejas and quarterback Troy Aikman, the Eagles coach became even more notorious for his cantankerous ways.
The first matchup between the two teams on Thanksgiving Day was one-sided, with the overmatched Cowboys getting a first-rate beatdown. The beatings weren't isolated to the scoreboard either. Throughout the day the players were chippy, and Zendejas left the game with a concussion after a hard hit by an Eagles linebacker.
The NFC East rivals met again in December in Philly that year. While the players never engaged in fisticuffs, obstreperous fans pelted Cowboys players, the Cowboys coach (Jimmy Johnson), officials and broadcasters with snowballs and garbage.
This sorry situation poured gasoline onto an already fiery rivalry. It was such a crazy scene that even the future governor of Pennsylvania, Ed Rendell, got caught up in the melee that day.
