Based purely on the fact that Brock is an accomplished amateur wrestler, I don't think you can pin the stigma on him of being just a "strong guy". There are a lot of guys in all the weight divisions that do not appear to have much technique and who tend to power (or try to) into their offense and defense. Why is it that Brock only gets the stigma?
I like seeing technique being used more than most MMA fans, but at the same time you cannot deny that technique and power can and do coexist, especially in the HW division. In the sense for how it is expressed in this and other threads, there is another way to think about the strength issue. If guys cannot beat a big strong fighter then doesn't that say that something is lacking in their technique? Why is it the "fault" of the big guy? IMO, big strong guys are a dime a dozen, but very few of them would be able to win a fight in the octagon based on their size and strength.
Another thing I would like to add is that this isn't the old days were a 300 lb guy is fighting a guy under 200 lbs. Frank Mir has his opportunity to bulk up and get stronger and/or heavier to try and nullify Brock's size advantage. That is basically part of the sport, especially in the HW division where the range of weights is so big.
I still feel that the reason people dislike Brock or think he is bad for the sport comes down to the fact that people don't like the fact a) that he used to be a professional wrestler and b) the fact that someone with that history came into the octagon and embarrassed two (nearly three) MMA veterans, one being a legend and won the title. To be honest, most of it comes off as bitterness in my eyes.
Mir added that he had to find sparring partners who are taller than Lesnar so he could practice trading punches with someone who had the same arm length as Lesnar.
And as for this, sparring with a tall guy with long arms is not the same as sparring with a guy with the same arm length, but a little shorter. If Brock is smart he'll be pumping his jab out there to make Mir come in on him. I don't think Brock has to worry about being taken down or knocked out and I don't think Mir will get the reset this time. He's in for a rough night.
