Try this then-
Get a friend (or use training mode and set RECORD) pick Zangief and green hand you. As long as it doesn’t knock you down (like EX green glove on hit), then it’s ALWAYS a free grab. No matter how much you try to mash tech, you can’t tech it.
it’s easier to do an HP shoryuken then try to tech someone throwing you after you land
If it’s on the ground, easiest counter is just to duck under it and hit em when they land.
