I love that this is an element of your position because it gives us insight your analytical abilities, or lack thereof. It's not just a cut and dried, "Who's career numbers are better?" case. Therefore, I'm left with a choice of two conclusions. One, you actually do think it is only about the bottom line on the back of the baseball card. Which, if that's the case, demonstrates what a great fool you are. Two, you know there's more to it. Which, if that's the case, demonstrates how full of dung you are. Neither conclusion makes me, or anyone else here, inclined to take you seriously.
This is a 2-month rental. That's it. No club options. The Braves traded away 2 compensatory draft picks and 2 months of Mark Teixeira for Casey Kotchman. Kotchman is a former 1st round draft pick himself, who flew through the minor league system, made it to the bigs by the time he was 21, and has already established himself as a slightly above average MLB hitter by the age of 25. He hasn't even hit his prime yet. Will he ever be a star? Not likely, but he's a safe bet. They traded the risk of those picks busting for a guy they know can contribute for at least the next 3 years while he's under their control.
They did not trade away 4 compensatory draft picks and 8 months of Nady/Marte for 4 guys who look destined for an MLB bench at best. Comparing the two as similar, is, like I said, comletely stupid, or completely disingenuous. In the past, I would have leaned toward the latter as it at least credits you with some degree of thought process, but now I'm inclined to think it's the former.
