I don't really feel deads unless I do them last. Too many bodyparts are involved - traps, lats, spine, butt, quads, biceps, forearms, abs. When a BB'er does an exercise we want to hit ONE bodypart at a time and kill it. If I do them last in a back workout I can use my fresh quads, hips and straps to overload my pre-exhausted back.
and? Nobody is debating whether deads build a thick back, although I certainly could make the argument effectively. Everyone points to Johnnie and Ronnie as having thick backs AND being deadlifters, thereby making the assumption that they have thick backs because they deadlift. Well, they all also train heavy too, so who's to say their thick back isn't simply from training heavy and not deadlifting? I built a pretty good back while rarely regular deadlifting. I've almost exclusively done high rep stiff leg deadlifts.
