Nope it IS possible. In fact Vinnie's time is far from perfect. It feels great and it's consistant, but it's human. The Zappa grooves where there was no click involved are VERY human. I'm not taking anything from him by saying this. Producers prefer this. Playing right on the click sounds too machine like. Jeff, Vinnie, Shawn Pelton, Kenny Aronoff, none of these guys nail the click perfectly. However, that consistantly behind thing you speak of, is very common. Take the click out, and the drums have a pocket. The word pocket means "behind" deep. Slip INTO a pocket. That's what that word means in music. Nailing the click is not slipping into a pocket.
So yes, it's the way most great drummers play. Gadd, Vince Keltner.
