I kinda doubt we ever see a close to "100% Vito" again. The finger injuries have not been great, but may eventually get better. His neck is always going to be an issue, unfortunately. This stuff is going to affect his training, which will affect his gas tank. To make matters worse, I have heard that Vito has long been a weight cutting machine. When you reduce his training time/intensity, making weight is going to be that much tougher and will take its toll even more than it has in the past.
That being said, he is still a tough out and Jax is to be commended.
