Austin Jackson is unproven, granted. But to give away his potential for a guy who hits left handers like a little leaguer is unforgivable. That's not saying that A-Jax will become a world-beater in a year either, but his potential was worth far more than a Curtis Granderson in a trade.
Granderson hit .249 in 2009 with a .780 OPS. To make matters worse Granderson hit a stomach churning .183 against left handed pitching.
Granderson plays a decent center-field, but he is by no means gold glove caliber. Austin Jackson had enough hype and potential to be a big centerpiece in a possible trade for Roy Halladay.
Giving Jackson along with Ian Kennedy and Phil Coke away for so little really limits the Yankees options with other big trades.
If this Granderson business turns out to be the "big move" the of the Yankees offseason, the word "disappointment" wouldn't go far enough to describe the missed opportunities that this year's market or available trades would have given the Yankees in their quest to build another dynasty.
