People might want to shoot me for this, but i'd much rather have Tejada and a Glovey McnoodleBat on one-year deals.
Tejada, contrary to popular belief, was a pretty good SS as soon as 2008, and i got to see a lot of him because he's "Captain Dominican" so we get a lot of Astros games, usually when Wandy Rodriguez pitches, or they face up against a Dominican SP.
2008 Tejada defensive metrics:
UZR: 9.3
UZR/150: 9.4
RF/G: 4.0
RF/9: 4.2.
2009 Tejada defensive metrics:
UZR: -13.9
UZR/150: -12.4
RF/G: 4.4
RF/9: 4.5
His range factor ratings actually improved in 2009, so a number of factors might have to do with his UZR decline, but the fact is, Tejada's defense is not what he showed in 2008 or 2009 but something in between, right around league average, and not a statue like some "Educated guessers" would lead you to believe.
