Nice move. Your were fine...I think my12floz has it analyzed correctly. A leg cradle is uncommon, it looks illegal, but of course it is not. I've seen two in 15 years and fortunately let them both continue but in each case I was giving them a close look and people were shouting "ILLEGAL" at the top of their lungs. There was no overscissors either, the pressure was with the joint, not against it. I'm sure the ref knows he made an error if he's looked at the film or been asked about it.
