One thing, though. Holding is, in some cases, hand placement, but holding is also a last resort to save your QB.
I think that most of the holding penalties we got where due to our guys getting beaten. I mean, they worked it out with Spitz pretty well. He's a very good guard and, under our coaching staff, hadn't had a holding penalty in 2008. And that's something like 1000-1100 snaps.
I think that the problem is, indeed, hand placement with Iutapi. If he's really as good as advertised (i'm still a little hestitant on his pass blocking), we can work that out easily and we'd have an elite interior O-line, immediatly, with Iutapi - Spitz - Sitton.
