Agreed. Also add in a few facts: DeRosa has had questions about wearing down when playing everyday both in 2006 and 2007. I remember a lot of people saying that he needed days off in the late July/August stretch when there were some injuries, but the Cubs simply couldn't give them because they needed him on the field too badly. Orioles fans say that Roberts is the same way, that he would have given better production if he could have rested a little more, but the Orioles needed his bat too badly. Now, the Cubs can do both. Roberts has a significant left/right split. If DeRosa plays 2nd against even half the left-handers, Roberts' production goes up. Having another good middle infielder in the mix at least allows them to consider playing DeRosa at SS at least occasionally, which would help. DeRosa had less than half the at-bats at 2nd base last year. In effect, Roberts will likely be replacing somebody else just as much as he is replacing DeRosa. There are other smaller benefits that I won't list because I don't want to make this an essay. Suffice it to say to just compare DeRosa to Roberts and conclude it's a marginal upgrade is not looking at how Lou has and will use DeRosa. When you add in the fact of how Lou will use Murton and Patterson (not very much), and the fact that Gallagher might not have a clear cut spot on this years team, it makes perfect sense to make this upgrade.
