All 1B are going to have a really high fielding percentage though just by virtue of getting credit for a putout on every throw from another infielder and that any ball hit sort of hard and bobbled can still be played into an out.
The real difference maker to me for a Gold Glover is their range and how many errors they save with their glove by scooping bad throws, etc. Texeira is excellent in this regard, so was Derek Lee. Davis doesn't seem bad at all especially for a pretty big dude but I'd have to see him in action more.
