It would seem that this strategy would work, but then again, how is it different from anything else? If you're keeping your innings down, just one bad start from a "volatile" young starter will ruin your WHIP/ERA for the week.
Personally, I like having a few good starters and a lot of good relief. That way one bad start doesn't kill you.
