Can you give me some of this history? Just curious as it seems counter-intuitive to me.
Tony Gonazalez has had at least 900 yards the past four seasons, with wide receivers like Eddie Kennison, Johnny Morton, and Sammie Parker.
Antonio Gates has had at least 900 yards the past three seasons with wide receivers like Keenan McCardell, Eric Parker, and Vincent Jackson.
Alge Crumpler has been a star tight end and everyone knows Atlanta's wide receiver futility. They have Roddy White, Brian Finneran, Michael Jenkins, and Ashley Lelie.
The Colts have Dallas Clark but they also have Marvin Harrison and Reggie Wayne, and as a result, (also due to some injuries) Dallas Clark has never had more than 488 yards in a season.
Jeremy Shockey has never had great wide receivers- Amani Toomer, Ike Hilliard, Plaxico Burress (who is good but very inconsistent.)
In 2004 Jason Witten had 980 yards while Keyshawn Johnson and Terry Glenn combined for just 1300 yards.
There are times where TEs can put up pretty big numbers even when playing with good wide receivers, but for the most part, when TEs put up crazy numbers they have less than average wide receivers.
I expect Watson to have a good year but when TEs are the primary receiving target of an offense it usually means the wide receivers aren't very good.
