In a word, no. Three-man rotations are murderously hard to maintain, and you will find your SP's running at 90-95% (at best) unless you get huge inning guys (over 350 IP). Usually you have to use someone like Elmer Steele as a combo long reliever and spot 4th starter to keep your 3-man rotation fresh, or roll the dice on a AAA spot starter.
You can squeeze Joss `08 into a 4-man rotation if you're willing to sacrifice one or two offensive positions and plug in your AAA players as starters there. One of my favorite $80 MM OL teams had a rotation of Joss `08, Pete Alexander `19, Doc White `06 and Bill Burns `08, and then I rotated AAA prospects at 1B and RF .
One of my favorite $80 MM OL teams right now has a 6-man rotation of SP's with between 150-175 IP apiece that cost only $27 MM, and they're very low maintenance and always pitch at 100%. I have $12 MM over for a 5-reliever shutdown bullpen and a full priced offense.
