that Kinsey report grossly overestimates the numbers. It is actually somewhere between 1-3%. Gay 'behavior' is an other issue.
Then factor in that participation in football is likely to select against gay participation (as opposed to say, ceramics and interior decorating*), and the numbers are likely to be even lower. Conclusion: TT is likely the only gay man in the organization (among players, coaches, player evaluation).
*warning: stereotype alert
And when you consider that TT's main job is evaluating tight ends, it kinda makes sense.
