That is really bad logic. You’re just looking at one-half of the story and not the other. What if it was a fluke season? What if ellsbury doesn’t end up being a high obp guy? 1 MLB season means he has more value than Kelly/Westmoreland doesn’t mean it’s better. I mean just as easily, we might trade Kelly Westmoreland and Buchholz become the next Grienke Sizemore and Hamels (in terms of prime production wise)
Ellsbury will NEVER be a complete player. Buchholz and Kelly have the “stuff” to be an ace. Westy has the “tools” to be a 5 tool player, and a great bat. Ellsbury doesn’t have that stuff to be a premiere OF, nothing more than a very good leadoff hitter at best.
