If pitching by committee means pitching by committee for all 5 games, then no pitcher should go more than a couple innings per game in any game. But you still need to try and get 5 or 6 innings with each of your starters on the week.
If that is the case, I could guess that he will have one of Rawls, Nezuh or McGehee starting all of these 5 games. Hell, Rawls could start 2 or 3 of the 5 and go only a couple innings in each, with Nezuh and McGehee picking up the other 2 or 3.
