I think this is Van Gundy saying to himself, "who's a good defender on my team...oh...Matt Barnes" without really taking any consideration into what the matchup will actually be like.
Still, I'm not sure that Vince Carter (a noted matador) would do any better. I think this is a great series for Ray and Paul to both go off. They'll likely need that, since KG is going to have a bit of a tougher time. While I still think he can post Rashard, it'll be harder knowing that Howard is lurking behind.
I'd also love to see Rondo penetrate early and get Howard into early foul trouble.
