His height situation is being overplayed. 7'1 wing span, I assume his standing reach is rather good, it just wasn't measured, has the body to take contact.
Mike Brown will mask the problems. They're both athletic enough and quick enough to play solid defense and are motivated. They just need instruction. Byron Scott literally did nothing
Kyrie is a different story though, he needs serious help.
They're not dried up old ladies, they're good to go.
I'm not concerned with Waiters. I think he just needs proper coaching. Bennett I'll agree, somewhat worried, but the offensive upside outweighs it for me
