I will try to help you narrow down this list. Out of these pitchers I like Ely, Francis, Sanchez and Vazquez. Out of these 4, I like Francis and Sanchez the best. I am not sure what to say about Vazquez. I had him last year and he was great but for some reason that Yankee uniform is his kryptonite.
I know some guys don't like to play this way, but with so many acceptable choices available, I'd just play the weekly matchup game and take 1 that faces the easier opponent. I start Richard every home game. Started Ely for his 2 wins last week but not his road game this week.Francis looks really good. Vargas has 2 home starts next week as does Ely. Matusz will be heading into a stretch where he faces the AL East way too much for my liking now.If you just look ahead and plan, I think you can drop Z & maybe Matusz and be better off with a couple of these every week. Now Francis & Ely probably won't remain FA forever, but it looks to me like the matchup game vs weaker opponents will get you a better ERA & more wins than just running the same guys out there week after week
