Are you guys sure you're not thinking of Dontrelle Willis instead of Loaiza?
I was pretty down on Loaiza last year, thinking he wasn't going to keep it up. Then I read about how he had added two new pitches. When he finished the year strong I thought "ok, now give the scouts all winter to figure him out and he's done" but it looks like he's pitching well again this spring.
for the record, I think he'll have an above average year, but not as good as last year.
Oh, and I'm for the Bonds side of this argument, although I'll admit you could argue either way with Kearns' potential and/or Bonds starting to finally wear down a little.
