Yes, they are different situation, but Fielder/Pujols are much better than anything the Cubs added that year. And while you did have core hitters to build around, you also had black holes at SS and CF to worry about. Those Cubs didn't have anybody like Starlin Castro on the squad poised for a breakout. And it's not like that 2007 squad was all that special. They still ended up no better than average at best on offense, being weighted down by a lack of power and patience (they ranked 15th in walks and 11th in HR, and were 8th in OPS). I don't think it will be hard for the Cubs to construct an average lineup, or better, following the addition of a stud 1B.
