You could say that about our entire Opening Day starting rotation. Dickey and Beurhle have under performed and Johnson, Morrow, and Happ have been injured. I'm not expecting every single guy to bounce back but 2 or 3 of them should expect some progression to the mean.
And as you said, Lawrie and Cabrera should expect improvement as well. Reyes is back and that adds a couple of wins over the junk we were trotting out there at SS too.
Add a 2B or 3B (depending on what you do with Lawrie), a C, and another starting pitcher and I think the team will be set to contend next year. Hutchinson, Drabek, Stroman, Nolin, and maybe even Romero will lead a group that is much more suited to provide rotation depth next year too which has been a big problem this year.
