I think you're extremely solid. I'd love to have that lineup! One thing I would consider is trying to trade for another dominant starter. I'm not in any sandbox leagues this year, but if their h2h scoring has remained the same, good starting pitching will rule. Check the scoring - if you feel this is true this year, too, maybe you can make a good deal before the rest of the league catches on.
Wouldn't want to be a pitcher facing those bats
