I think of Deduno and his injury history like I thought of Jordy Nelson when I drafted him on my fantasy football team this year. Jordy had had some injury problems the last few years, but when he played, his per game fantasy numbers were near the top of the league. He went in the 5th round because of those injuries, but I was happy to take his 15pt/game when healthy and was prepared to slot in my 4th WR if those injuries came, which they never did this year (although Rodgers' injury felt like a Nelson injury). Deduno, when healthy, will be our 4th or 5th starter (like Jordy was my 3rd WR) and he may well play above that level, until his next injury comes. When that injury comes, the Twins will just go the their heap of AAAA starters (4th WR), play some matchups, and ride that guy until Deduno comes back. This way of thinking doesn't work when we are talking about a #1 or #2 starter, like it doesn't work with a RB in the fantasy football example, because the drop to your replacement level guy is too great for it to be worth the risk.
