I'm a big proponent of balance in your lineup. You really need at least 2 LH bats, and the Cards only have Carpenter. From that perspective, adding Goldschmidt is a bit weird as he's yet another RH bat. I think it would be a better use of the Cards resources to try and trade for someone like Thames. Them acquiring Thames is wildly unlikely for so many reasons, but the primary reason is the balance. There are plenty of guys similar enough to Thames in the league though. The Cards could bat Carpenter 2nd and Thames clone 5th or 6th against RH SP...those 2 guys would rarely face a lefty until late in the game. They have enough depth to let Thames clone only play against RH SP and move Carpenter or someone else to 1st against LH SP. If the Cards make a FA splash of Goldschmidt plus a LH bat, and the Reds acquire some high-end SP as they are rumored to be targeting(coupled with DJ making their rotation better as is)...the NL central could be ridiculous. The Cubs would probably still have the best roster, the Brewers made the NLCS, and the Pirates roster really isn't that bad. To end my rant, there aren't many teams in the NL that really aren't trying to win now or are positioned to win very soon. The Marlins, maybe the Giants depending if MB is traded...who else? The Padres have a ridiculous farm system with many top guys in AAA or at the MLB level already, and they are reportedly looking at win now moves. They could be good this year. The Pirates made the move for Archer last deadline and really aren't losing much to FA. They tend to be solid/scrappy, not exactly what you want to be but for sure not a tanking team. The Reds are positioned to be good as soon as they get some SP. The Mets appear to be trying to bounce back with recent moves. The Nationals still have a very good roster even without Harper.
