If you arrive at a point where you would make the switch, youre basically opting for someone who could be good vs someone you know is bad. Thats where one is at when they are ready to make such a decision. Its not bad to have options. Right its not bad to have options thats what the minor leagues are for. However from your original post, you are basically advocating giving somebody a spot start or 2 to see this option, which is absurd. You dont take starts away from someobdy, just to give a kid a spot start or 2, while you are in a race. If somebody gets hurt, then by all means, move Gallagher, Guzman, whoever into the rotation and see what they can do. You seem to be really wrestling with my original post. Ive cited it for the benefit of the discussion. Anyway, no, its conceivable to let one of the young guys start during a stretch of games situated closely together or even if not, you can just give everyone an extra day between starts. Not a big deal considering the dividends it can pay in the long run. And Im not as grim about their chances as you are. I feel like Marquis is going to struggle in half of his starts now...and that goes for Rich Hill too. Thats a coin flip so why not cultivate options while giving guys an extra day of rest? Im not struggling with anything in your post. Teams that are contending dont just give spot starts here and there. Its that simple. And really what will 1 spot start from Gallagher tell you? Numerous rookie pitchers have made a spot start and looked like Cy Young(Ryan O'Malley) and then go on to be nothing special.
