Last years team was competitive till the ASB. Based on first half stats:
1. The rotation is deeper but without Dickey
2. The bullpen is significantly better ( Rauch lost 7 games by June), etc.
3. The infield is better since Ike was a zero through June and Murphy was an adventure as he adjusted to second base
4. Catcher is improved. Buck calls a better game, won't lead the league in passed balls and if he and D'arnaud drive in 50 runs, it will double Thole and co.
5. The outfield will be improved. Same candidates less Bay and Torres. Addition by subtraction. Added several unproven outfielders with potential - Cowgill, Brown .
6. Management willing to add a piece if team is competing
7. This year, reinforcements are on the way - Wheeler, D'Arnaud, Mejia, Familia, Den Decker, and who knows???
Yes, things have to break right. They did last year for 80+ games. If the team had added a key piece, Santana stayed healthy, and the bullpen not undergo a nuclear meltdown, it may have ended differently. There is more depth this year.
