This is my idea of aiki. Ueshiba doesn't evade, he uses power to affect the attacker. There is no evading a tackle here, no attacker spelling his own demise. Ueshiba has power, control, and removes the attackers ability to attack, effectively rendering the attacker powerless. Many of his students talked about his power and their inability to understand what he was doing. I don't understand how evading tackles equates to all that?
Mentally, Ueshiba said he was the Universe and who could overcome that? I don't remember him saying that he evaded his attackers until they created their own demise. Physically and mentally, I think Ueshiba's aiki was something different than a receiver evading tackles. But that's just me. YMMV.
