Pump, I dont know if you actually believe what you are saying but it seems nobody else does. He has an advantage, simple. Typical takedowns-single leg(could hit but very unlikely as he is sitting on it), double(impossible), duck under(almost impossible as he is basically laying down), front headlock spin around(very unlikely as he only has to spin while the other guy runs around), throws(most likely but extremely hard as his upper body is way too strong and him laying on the mat gives no opportunity). From the bottom-stand up(he just latches on with his strength), switch(almost impossible, there is nothing to grab). On top it has to be all arms because you cant leg tilt a guy like that, and those arms will stop anything you try. Yes he has an advantage, to say other wise is just silly.
