Cabrera is among the very worst defensive SS's in the majors. He hurts our defense so much at SS, so he needs to be a middle of the lineup bat at SS to be worthy of any halfway decent reputation.
The Mets complain about the pitching, they were saying that we couldn't worry about adding hitters to the lineup because the pitching wasn't good. Part of why the pitching isn't good is because their two SS's are pretty much the two worst defensive SS's in the majors. The problem at SS wasn't just Cabrera, it was also Reyes, who is equally bad. They've had an MLB ready GG caliber SS sitting in AAA, but they preferred to punt the season. There is not a good infield defender on the team, they've had corner OF's playing CF because they didn't bother getting a CF'er, the LF'er is lazy, no wonder our pitching sucks. We have below average fielding at every position.
