For me, the saddest day was when Jimmy Johnson left/was fired. I knew it was the end of an era.
It was a sad day, but I can think of many worse days in Cowboys history.
Irvin had had a great career. And that injury didn't prevent him from living a normal life today. It's not like he was paralyzed at the beginning or in the middle of a great career. It was an injury that came at the end of a great career and doesn't affect him much today.
Side note. When reading this thread I started exploring Irvin's stats and then ended up expanding my search to look at the stats of all the WRs drafted with Irvin in 1988. By my quick count the WRs in that class ended up with at least (I didn't count anybody I never heard of or remember):
6026 receptions
87,777 yards
535 TDs
Here are the top 14 WRs from the 1988 draft class in terms of stats:
Ice Bowl and V then 13. The Catch game. 94 CC game SF. There were some other notables like the two losses to the Browns in the late 60s and the loss to the Rams and an inferior team.
