#3 Age
At the age of 32, Graves still has so much more to learn within this business.
His early retirement from in-ring wrestling could well end up being a blessing in disguise, as he could have at least a decade or more left in the business as a commentator if that is the direction that he chooses to go down.
With more years under his belt, he will continue to grow. Considering that commentators don't usually hit their prime until much later in their careers, we should all be very excited about Graves' future.
You can tell how consistently fresh and vibrant Graves is feeling on a week to week basis, and it's good for someone like Cole who is approaching 50, to be able to bounce off someone like Corey.
The two work well together and can learn from one another as their partnership rolls on, meanwhile, Graves can also continue to use the 35-year-old Saxton as something of a test dummy for future broadcast colleagues.
Speaking of being vibrant, this next point is crucial to his development.
