re: What would you say is more embarrassing: Getting stiff armed or dunked on?

Being stiff armed is way worse.
Im speaking as recipient.
In both instances i was recipient, the runner scored td. You are splat on ground watching runner dash to goal.

Being dunked on is commonplace.

Few defenders can stop a dunker at the rim.
It never bothered me.

I dont see dunking as an accomplishment unless you are spud webb sized.
