Here's the problems I see with it. Since Wood requires several days between these appearances(as would most if not all pitchers), you are essentially playing with a 24 man roster on the days he doesn't pitch. You don't have the flexibility of a 7 man pen or of a 6 man bench. Secondly, if Wood is ineffective and needs to be replaced in any of the outings, it further taxes the pen that Wood is basically acting as a 5th and a half starter for. That said, I'm not against the idea per se, I'm just not convinced either way. Exactly. If he's only pitching on the days that Maddux starts, that means on the other 4 days, we're playing with a 24 man roster. In addition to that, Williamson won't be available every day. So let's say Wood pitches a game that Maddux starts. If Williamson pitches the next game, we may be automatically down to a 23 man roster for the next game or two. Then if our starter in the next game gets knocked out early, our bullpen is in shambles. In theory it sounds pretty good, but in reality we would have to count on Wood being very good on the days he does pitch, and our other starters being able to consistenly work fairly deep into games.
