IMO the best wrestling technique is an outside single, similar to what Randy Couture did to James Toney. Once you get the outside single you use it to kind of circle the guy down. Some people prefer to pull it straight up but I always found more success doing what Randy did and kind of circling down. You can also use a trip when you grab the single.
Is this the same technique Sonnen used to take Anderson down on the first round of their second fight? I thought that was brilliant technique, the way he circle making Anderson to lose his balance?
