What we all know about what happened is that Fedor appeared to attempt an armbar and Rogers succumbed to the manuver, losing his otherwise advantageous position.
You say he got out of an armbar... he was never in it. Had he been, he'd have lost to it by my, and i think any reasonable statistical, estimation.
i think you read far too much into Roger's jits def. Your entire argument is based on him losing a superior position and Hendo is no where near as strong as Rogers by any reasonable assumption. And while he is far better a wrestler than Rogers, Fedor would be a terrible fight for Hendo who could otherwise dominate competition at MW and LHW if he got through Garard.
