I honestly do not think Colby Rasmus is going to become the second coming like so many people say he is. All these people (in the media) criticizing the Cardinals for the trade...what has Rasmus done to drive his value up? Seriously. Look at his numbers. Add that to the fact that he had a terrible situation with TLR and rival GM's knew he'd be ripe for the taking at a cheaper cost. Don't get me wrong, we didn't get back quite what we could have, but it doesn't sound like there were many options for Mo to look at. There were reports he was trying to squeeze a staff ace out of Tampa Bay but they wouldn't budge on a low ball offer.
Personally, I wasn't that high on Rasmus. He reminded me of JD Drew, minus all the stupid injuries. A lot of hype, decent numbers, but ultimately just a giant headache.
I know Rasmus is only 24, about to be 25. He could be a late bloomer, but he could also be that fringe guy that was always supposed to be something great and never panned out to be what he was projected to be (see: Gordon, Alex).
When Pujols was 25, he won his first MVP and had been an all star multiple times. I bring this up only because Pujols said Colby was a more talented player than Albert was. And in terms of tools, he's probably right. But from what I've read, it doesn't sound like Colby has the mental fortitude to drive himself to play at a Pujols-level. That holds especially true after Pujols said that Colby felt players were 'picking on him' when they'd try to give him advice.
Time will tell of course. It's stupid to grade trades the day after they happen. I think the Cardinals got some good pieces for this year, but will be interesting to see where they go in the future.
Also, if Wainwright hadn't got hurt, this trade wouldn't be needed.
