Kick catches- i cant visualize this 'drip pan' catch he is talking about. scooping hook is common.
A san shou guy was saying-
"There are a wide variety of catches and hooks which can be used against kicks. The two most common are the "drip pan" catch against the round kick and the scooping hook against the front kick. Both require a certain degree of courage to execute. However, the advantages of a successful execution are many. Kick catches set up throws, counter strikes, counter low kicks and knee strikes.
The popularity of the round kick in most kickboxing styles makes the "drip pan" catch one of the most important. The "drip pan" involves blocking the round kick with the forearm and catching it by reaching under the block with the other arm. The slight deflection is then accompanied immediately by an overhooking of the foot. The foot will be tightly secured under the arm. The "drip pan" catch is generally followed by a throw or a cross. "
