Cubs sign Burnitz

I've learned to trust Jim Hendry because of all the great deals he's been able to pull off in previous years, but I do not understand why he signed Jeromy Burnitz. Last year Burnitz hit 322 with 24 homers ands 68 RBIs in the light air of Denver and .244 with 13 homers and 42 RBIs everywhere else. Last time I checked Chicago is not in Denver so I guess we can expect the latter.
