I think the person to compare Morrison too isn't HBK, but Kofi Kingston on Raw. As far as non-character things go.
And tbh, to me they are both just 2 WWE versions of Jack Evans. Spot monkeys who can around the ring. So yeah, I think Morrison sucks all around, including his horrible mic-skills. His character doesn't matter because he's unlikely to be able to cut a good promo.
No HBK.
