Problem is with guys like Lewis, or Buxton, they are never 100%. At any nano second after returning to the line up at 100%, they are more likely than 99% of other players to get hurt again in rather short order. Just doing normal baseball activities like running, accelerating or you name it, seems to be too much for their fragile bodies. With Lewis, it's not how much time he will miss in any given season, it's how many games he will actually play. When he does come back, he's a ticking time bomb until he explodes again.
