Okay, I'll fully admit my football knowledge isn't all that worthy of starting such a discussion, but I do pride myself on being acutely aware of trends in the physical make-ups of various sports and their positions. We have linemen regulalry getting up over 6'6" (6'8" in the case of orlando pace if i'm not mistaken) in what is largely a leverage position. Additionally, QB's are getting taller and taller, not to mention wider and wider. Most telling, the size of WR's has skyrocketed...with Randy Moss seeming to be the prototype for the future. All of which prompts me to ask, why have tight ends, who traditionally have held a serious size advantage over their WR counterparts (even as the line between TE and WR became blurred in the 90's and continues with no sign of abating).
In just about EVERY sport we see this trend in increased size, for obvious reasons. It would appear to me, however, that TE's in the NFL have not kept pace (both within and without the NFL) with this trend. Why, I ask, do we not have 6'8", 6'9", or even 6'10" tight ends. Clearly, as basketball, and to some extent baseball and trace other sports, has demonstrated their are individuals over 6'8" wholly capable of fulfilling the athletic requirements of a tight end.
My own personal theory is that, as the lowest paid "skill" position in the NFL (witness the tony gonzalez fiasco) those with that kind of size and athleticism gravitate very early (and very sensibly) towards the power forward or center position in basketball, where salaries are higher, marketability more promising, and careers relatively longer. I'd like to hear all the football players (past and present) chime in though, as this has been on my mind for quite some time.
