Drabek threw at the end of last year (in the majors), and was hitting 95mph and averaging 92.7 on the fastball. Unless he blows out the arm a third time, he'll almost certainly pitch in the majors again (and I suspect he may break camp as one of the starters).
The depth next year looks to be fantastic, which will probably (but hopefully not) be critical to our success. Now that we have it, we'll probably only have to use 5 starters all season. Murphy's Law and all that. I really believe we only need one more guy "guaranteed" to give us 200 innings. We should have the budget for it, or at least be able to make room for it.
