Yeah but there were also people (like me) saying that Hill > Parker was completely moronic.
Kawhi's situation is different. He is a legit lottery pick (ok, he was drafted 15, just outside lottery territory, but you know hat I mean), he doesn't have a complicated health record like Blair, he's not a tweener like Hill. He's a legit SF, defensive-minded, right now playing a strict role on the team but showing flashes of brilliance when let loose. I'm not saying he's going to be an All-Star, but at this stage it's certainly not ridiculous to think so.
