Well, perhaps Theo Epstein and Jed Hoyer haven't been quite as idle as we think they've been. By staying in the race for Albert Pujols -- or at least allowing people to think they were in the race, he was able to drive the best hitter off the best team in the NL Central. The Cubs just picked up about 6-7 games on the Cardinals without signing a player.
It also remains to be seen how the Pujols signing affects the market for Prince Fielder, does Seattle up the ante to try and compete in what is suddenly a loaded AL West (well, at the top anyway)? The Cardinals are expected not to make a run at Fielder and instead they will fill the gaping hole internally with Lance Berkman. Rather than Fielder, I could see them making a run at Carlos Beltran to take Berkman's OF spot.
Also, if the Cubs sign Fielder themselves, does it mean they can suddenly contend in a vastly weakened NL Central?
Then there is the Angels signing of CJ Wilson and how it affects the Matt Garza trade talks. The Angels have seriously upped the ante in the AL West and may even be considered the favorite right now over Texas. They stole their best pitcher and have picked up the best hitter in baseball. The Rangers really need to upgrade their own pitching staff to keep up. They may make a play for Yu Darvish, but wouldn't they rather have an established pitcher with a known track record of success in baseball's toughest division?
The Cubs have every right now to go for the throat and demand Jurickson Profar. He is the closest thing to a sure thing as there is in that system. Texas can either keep him and wait while the Angels steamroll them for the next 2-3 years or they can make a move now. Of course, they can turn to Gio Gonzalez or Jair Jurrjens, but neither is the pitcher Garza is. Garza has the potential to head straight to the top of that rotation. In fact, if you went by WAR or FIP, he'd be their #1 starter.
