Napier should at least give up a foul after his crappy 3 and not watch a layup. He's not vital any more, so his foul trouble isn't an issue.
If we're playing 3 guards, there's no reason whatsover that our bigs should be the ones continually getting the ball at the foul line. And the one time Lamb actually got it there, he was scared. Try Giffey in there a couple times - Roscoe (who played hard and deserves some minutes) had one blocked and shot another over the backboard.
And if we're playing 3 guards, we shouldn't be packing into the paint on penetration and giving up unguarded 3's over and over.
