Again with the strawman…sigh.
Ibaka, like Eaton, has proven in other ways that he is an adequate defender. Thus, one guy dunking on him doesn't tell me much.
Randle, unlike the others, has not proven that he is even an adequate defender, and thus, the guy dunking on him shows me more.
Again, this is a guy who by the tests can jump, has a decent wingspan, and everybody talks about his motor. Yet, his defense still sucks. It's not just subpar, it's ****. So is it because he's just bad at it, or because he isn't putting in the effort? If it's the effort, then we have to question his motor. If it's talent, then we have to wonder how much worse he'll be at defense in the NBA.
I'm not saying Randle is bad, I just don't think he has the talent to be a top player on a good team. I'm not saying that a guy like Vonleh can be a top player on a good team, but I think he has a better chance to be one of those guys than Randle does. Randle, while good, has a low ceiling, and IMO, an average floor. Vonleh has a lower floor, but his ceiling is much, much higher. We already suck, so we might as well take a chance on a guy like that. Just my opinion.
