Ha, it's funny you sent that link!
I found a post shortly thereafter that describes what happened to Joel's ND offer after he declined Army:
"When you go into the Carousel, you get your first offer, in this case it was Ole Miss with other choices being UCLA and Rice. I was going to take UCLA, so I turned down Ole Miss. Well, when that first offer was nixed it changed the offers out there dynamically making my second choice be Louisville instead of UCLA and my third was Tulane I think. So, keep in mind, you can keep your current job pretty easily. If you decline the first offer for an HC, if you get one, the other offers will change too."
