Pass Interference

I was watching the Michigan State v. Nebraska game tonight and I thought the refs made a great call on not calling defenvise pass interference on MSU.  The offensive player posted his hand on the defenders chest.  The defender did hook the arm but did not reach for it.  In my opinion, the offensive guy infuriated contact.  If anyone should be flagged it would be him.  The announcers made a big deal about it but call it fairly.
