Technically speaking, it's impossible for more than two guys to line up at tight end. By definition, the third one has to be in the backfield. All our talk about three-tight-end-sets is really about personnel selection (and the resulting match-ups) rather than Xs and Os.

True, of course, but everyone calls it a 3 tight-end set when the third tight-end-type player lines up at a wing position that is immediately next to the end, set back the minimum distance from the line to be considered technically in the backfield.
