A lot of people are asking why it went from around -180/-200 to now like -120... Ill give the coles notes version of why and i might be leaving out some stuff but very quickly a list.
A) Brocks long layoff
B) Brock was very sick, lot of critics are wondering if he will come back strong from it.
C) Brock lost a lot of weight, a shitload, people are unsure what this will do. He could be faster but he could loose a lot of strength and that is what he does best which is bully smaller opponents but Carwin is apparently as big weight wise as Brock.
So pretty much those are the main reasons why brocks line has gone down that i know of. Of course a bit goes to Carwins hype whether warranted or not.
And before some of you jump on what im saying, these arent all based on my opinion. This shit is coming from what ive read or from what i have seen on TV in interviews and such...
