He certainly wasn't great, but was he really that awful? .258/.322/.435/.757 BA/OBP/SLG/OPS, 24 HRs, 87 RBI and played a decent right field for 1 year/$4.5 million. According to B-R, Burnitz had a -0.9 WAR for the Cubs that year. So to answer your question, yeah...he was pretty bad. Fangraphs had him at a 1.9 WAR. I have no clue if one site is better than the other.
