Sports games on the DS

Okay, so I'm a new owner of a DS and am loving it. One question I have for the folks who have had theirs longer: are any of the sports games worth my money?

I've heard rumor that the Madden games really stink. But, FIFA 2006 has gotten some respectable reviews (and is not super expensive at $20). Anyone have any experience they can share?

Short answer: No.

I have played a few sports titles and none of them were worth a darn. The small exception is Fifa 06. It is really simple and arcady, with poor A.I. and a weak league mode. However, it was still kinda fun and made a road trip a little better.
