Seems like you got a lot of value there. The combo of Rutledge, Kipnis and Middlebrooks for 11 bucks is a steal. Your starting pitching should be good enough to carry you for a while: Kershaw and Zimmermann are very good as a SP1 and SP2, whereas Kennedy could be very useful (and at the very least is reliable every 5th day). Haren for 16 seems a bit much, but since you had money to spare, he's kind of a "why not?" pick
In short, I think you splurged in the right places and was able to get some really good value for a lower cost. I can't say you're a lock for first (as I don't know the rest of your league), but I like a lot of the guys on your team.
