This isn't necessarily true. There are a lot of factors that go into injuries (diet, hydration, weight management, training methods, etc) and history can be a factor depending on the injury.
I like Sammy, but he wasn't 100% for a lot of his time here. What the future holds no one knows. But it's funny how many people are dead set he'll be Julio 2.0. That's just as much of a reach as saying he'll never be healthy.
Those games count now I heard.
