At one time even Rajon Rondo was an unproven rookie. Your argument that Enes Kanter right now is unproven which means he isn't valuable is absurd. He's leading all rooks in rebounding and should be playing more minutes. You can thank Tyrone for that. As for Rondo, really good rebounder, passer, and defender. Terrible shooter. You might have a point if we were a Rajon Rondo away from competing for a playoff spot. We aren't. It makes no sense to make that deal unless it puts us over the top. When I say over the top I mean it makes us not only a playoff team but an actual contender. Good PGs can be had via the draft. Maybe not as good as Rondo, but good enough to get the job done. Good bigs are tough to find.
