I don't think switching up the lineup for one game is good for us, especially as well as we've been playing with this particular rotation. Like others have said, Barnes being out really helps, because IT can guard Rush.
It'll be interesting to see who they have guard IT. I would put Klay on him, because he's been known to have problems with bigger, lankier defenders. That also lets Curry rest a little more on defense not having to guard our best offensive player, though chasing AB around screens isn't much better.
