The only way you have success over the course of the season is if you can go through your rotation and get quality starts, at least from four of them, three times in a row.
Coming to spring training and filling three spots in your starting rotation is not good. I don't care how you look at it.
A lot of teams are using emergency starters this time of year, ... but we have two 'openings' in our rotation instead of just one and, right now, they come back to back.
