If you watched the games last year, especially towards the end, you'd see that (regardless of stats) Chacon and Small are completely different.
I should also point out my other reason for being such a huge Chacon supporter. I was at his Yankee debut. Ever since then, he's just one of those players that , as a fan, I feel a weird connection with. I have to root for him.
(Side note: That was the greatest game I've ever been to. Starting off teriffied at what this "Chac-un" guy would be like against the Angels and just a few hours later giving him a standing ovation, along with 50,000 other fans. And it didn't hurt that the Yankees rallied from a 4 run deficit in the final two innings.)
