Atleast that's what Chiefs and former Texans RT Eric Winston said on 790 this morning. I'm paraphrasing, but that's close to what I heard, so I'm throwing in the link to the Winston podcast this morning if you're interested ?
This conversation with one of the 790 guys was in the context of the marching orders that Saints players got from their DC Williams, and Winston was relating how some of the Texans lineman weren't thrilled with cut blocking (legal technique used in ZB but unpopular and dangerous), but were threatended by ZB guru Gibbs with unemployment if they didnt use that technique. In other words, NFL players sometimes find themselves between a rock and hard place to.
