I didn't learn much from that fight other than Brock still looked really strong, considering how easily he manipulated his opponents arms and legs to get a full mount. Other than that, there wasn't really much to say.
I think having Brock in MMA is good for the sports as it will attract prowrestling fans. I don't see him as championship material though, although I am sure he'll get the opportunity if he wins a few, just because his name still has a lot of value.
If Dana did bring him into the UFC, I don't think he would stand much chance against Randy Couture if Couture was still champion as I beleive Couture is the better wrestler and striker. Brock would have youth and power, and I don't think that's enough.
