Agree with you on the undiagnosed heart condition. It was hard to watch but impossible to look away at the same time. Like I told my wife last night, if you were to have some sort of medical emergency being a player in the NFL and on the field is probably the best place to have it outside of being in an actual hospital. Thank God for the actions of the on-field medical staff.
I was impressed with the ESPN announcers for how they handled the entire situation when there is literally no news and nothing to say.
I think the NFL is getting a bad rap because of the speculation they were going to give the teams 5 minutes to warm up and continue to play. I think the NFL knew they had to postpone the game but had to figure out how to get to that point. It isn't like a Little League game where you just call it and come back next week. There is a lot of moving details, and while it is trivial right now, the actual game is a big game in the realm of the season, and I am sure they want to check with all parties before making official decisions. They did the right thing by temporary suspending it to give themselves time to talk to all their stakeholders in the situation - coaches/teams, NFLPA, etc.
