So You wanna lay some money on UFC 91 and try your luck?
Frankly, this is not a very good card for betting.
The pick that seems to make the most sense is to go with Randy at the sites that have him as a +120 underdog.
Randy thrives on being the underdog and lay down a hundred and you will walk away with $120 profit.
One thing to keep in mind is Randy has more ways to win than Brock.
