There is a fair amount of information here, although it doesn't seem like you can query the data in any meaningful way.

Does anyone else use a better source?

I think that sherdog has the most comprehensive stats you'll find anywhere. AFAIK there's not a lot of stat info out there for MMA, not yet anyway.

I personally feel like stats won't make too much of a difference when handicapping. You gotta watch fights and get a feel for each of the fighters. Plus stats can be very misleading, a stuffed takedown is way different than a rocked fighter trying to hug a leg, yet they each show up as a missed takedown. Just my two cents

Yeah Sherdog is pretty much it.. MMA isn't really about hard data though, at least it won't help you win much compared to knowing the fighters, their styles, their training, recent performances, etc.

Yep, I wish the stats that the UFC shows before some of the fights was accessible to everyone.

Fightmetric is a sweet site for mma stats.
