If the Rockies' goal is winning the division, it seems prudent to compare what the Rockies have vs. their divisional foes. Luckily for us, Brendan Scolari at TrueBlueLA is doing the work for us.
A quick glance at the Rockies lineup suggests that 2B is the Rockies' weakest position. Yet the Barmes/Baker platoon ranks 2nd in the division behind LA's Orlando Hudson and Mark Loretta. The statistic of analysis is WAR (Wins Above Replacement), which takes into account offense AND defense.
In fact, Clint Barmes and Baker rank 2 and 3 in the division respectively regardless of their platoon split playing time, behind Orlando Hudson.
Conclusion? While 2B is often cited as the weakness of the Rockie line-up, in context it is quite strong. Granted, 2B is a weak position across the board in the NL West, but perhaps we shouldn't be worried if the team's weakest offensive position is one of the best in the division by comparison. And this doesn't even include any contributions Ian Stewart will make.
Now if only Rockies pitching compared as comparably.
