From what I understand, RV has an injury to his hand that will never get better. A few years back he broke his wrist and didn't deal with it correctly. The scaphoid (aka navicular) bone in his left hand was fractured and did not heal. That particular bone has a poor blood supply and it can be lost in the injury resulting in the bone dying. It results in a progressive arthritis.
In the last year RV has had a few get offs that started with him losing grip on his left hand. He just has not had his normal overwhelming speed that no one could match. I used to be that no one would pass RV. This year he has been passed on more than one occasion.
That said RV seemed slower in this race than normal. I would not be surprised if he was sick.
What about Dungy. No more Mr Nice guy from him.
