Comparing a TE today to one from the seventies is hard to do, the game and that position has changed quite a bit. He definitely has durability issues. But all I am saying is if you were to look at production per game or production per year even (which would hit him for his durability) I think you will see his yards and TD's per game/season is at the top of the list. To me he is the hardest TE to cover I have ever seen. He catches balls and scores TD's when he is completely covered, he just boxes them out with that enormous torso.
