As Emin pointed out, Taveraz's 2007 OBP was based on a BABIP of over .370, not something that is likely to ever happen again. Heck, even his 2006 and 2005 were BABIP-lucky. (source
Last year's production wasn't a bad year, it is what you can expect from Taveraz with average luck. Since he has no plate discipline or power, BABIP is unfortunately the sum total of his offensive value. One of these years he is going to have a BABIP-unlucky year. I do not want to be the team wasting ABs on him when that happens.
