Well, as long as we're naming names, also selected in the first over the past several years were Tony Gonzalez, Dallas Clark, Jeremy Shockey, Dan Graham, Jerramy Stevens, Todd Heap, Bubba Franks, Anthony Becht, Ben Watson, Mark Bruener and Keith Jackson, and Alge Crumpler was just a few picks from being a first-rounder. While not all of them are superstars, there is a fair number of solid stars in that group.
In 2002, three tight ends went in the first round. Those three teams were the Giants, Pats and Seahawks (all playoffs teams this past season). And two teams picked TEs in the 1st in 2004, of which one team was in the playoffs (Pats again) -- the other was the Browns, and it is hard to say what would have happened if Winslow was not such a giant idiot.
My take is that a 1st round TE can be a superstar, and history does not prove otherwise.
