Touching the rim in any capacity on a shot is an auto-goaltend. Grabbing the rim is a tech. They're saying he used the rim to pull himself up...auto tech. He did grab the rim. There's nothing to discuss about that, other than was it inadvertently, but you still can never grab the rim.
Players get techs for grabbing the rim or hanging on it after a dunk. It's always been the case. Touching the rim is a goaltend. It just so happens this was the same play, but one doesn't negate the other. Blame Bam for that play
