I've done the same searching as you and for some reason, HTS is the ONLY place to find any tweaks. Almost seems like they kick back to anyone who might have the tweaks so they don't post them anywhere else. Very disappointing.
I haven't seen 2k2 yet so I can't comment on that one. But, I own Madden and I tried Fever at Best Buy. Of the two, I thought that Madden was more responsive. Mr. Madden's comments get a bit annoying, but that's really neither here nor there. One thing to note about the 2k2 review on Gamespot...
I bought Madden based on the reviews which were slightly higher than Fever. The other day I played Fever at Best Buy for a little bit and found that I liked Madden better. It seems a little bit more responsive, although if you don't like Madden's commentary, that opionion won't change.
