The Cubs could have a totally different looking offense this year. They were really bad in OBP last year, and gave a ton of the AB's to sub-.300 OBP guys. If Montero can stay healthy, and if Bryant earns his way up, (likely), and if either La Stella starts at 2nd or else Alcantara improves a lot, it seems well possible that we could/should have .300-OBP regulars at all 8 starting positions. That could be a big change. And while that may seem like a modest standard, the Cubs weren't the only team playing a lot of sub-.300 guys. The NL OBP average was only .312, and there were six NL teams with a team OBP of .305 or worse. The Cubs at .300 weren't even the worst in the league. Of the five teams with a .320 team OBP, four of them made the playoffs. (Colorado didn't. The world champion Giants of course were the NL team who slipped in without a .320 OBP.)
We'll see, but I'm not sure it's unrealistic for the Cubs as a team to be more .320's than .300 this year, if Montero can stay healthy. (If it's David Ross four days a week, and whatever scrub we've recalled from Iowa the other three, catcher could be a total black hole. That is, unless we keep Castillo....)
