These are fair concerns.
I think that having Cicconi, McMahon and Van Belle back ameliorates many of these concerns. Eskew and McFarlane should easily be able to provide 2-3 strong innings per game; considering that they should be buttressed by elite batting. We have Federman back for a third year and still have 3-5 other serviceable pitchers as well.
Am expecting a top-10 team and 2-3 series losses for the year.
The past three teams improved markedly during the course of the season, so I expect that to continue.....
I think the key is having McMahon available for the post-season. He missed a plethora of games the past two seasons and also suffered a serious injury his last year in high-school.
