Umm, no. What Theo did with the Cubs is an entirely different situation than what Dombrowski is doing now. What Theo did with the Cubs is what Ben was in the process of doing here, but was not allowed to follow it through to fruition.
Theo completely tore down that team and rebuilt it from the ground up. Dombrowski is taking 'spare' parts from the team that Theo and Ben built here to fill in the holes, something that I believe Ben would have done had he not been fired.
If I'm not mistaken, every player on the Cubs' active roster is a Theo acquisition over 5-6 years of building that team. Many of those were acquired by trading away, not prospects, but MLB active MLB players.
