It truly does always seem to happen in threes

I was the first person up in our house Saturday morning as I had to attend a lengthy meeting.  Thusly, I was the first person in the house to receive the word that Chuck Noll had passed away.  My husband, being a life-long Steelers fan, was saddened to hear it.  Yesterday, upon awaking I learned that Casey Kasem had passed away.  Today, my news feed shares the news that Tony Gwynn had passed away.  Strangely enough, yesterday upon learning of Kasem's death, I had the thought that there was going to be another one...these things truly do seem to happen in threes.
