I wouldn't exacty agree with the headline here. I mean, maybe it's "technically" right...but still. Anytime you lose a player like Cam, there is going to be some sort of "problem" replacing him...
The odds of someone stepping up and "replacing" his talent set, are about the same as someone stepping up and replacing Bo's talent set.
I don't agree there has to be a "problem" replacing a once in a lifetime player. Or rather, it's no more a problem than any other team has finding such a player. Games, SEC Championships, and National Championships have been won with lesser players than Cam.
That said, you do have to have overall talent to win, but you don't need Cam type talent to win. However, it certainly makes it easier.
