Some say playing sports is like a fraternity. A bond develops between people who have a common goal must work together to achieve said goal. If we are sticking with the fraternity comparison, I would guess if you were in the NFL and were drafted in the same year together, it would be like your pledge class.
For Pittsburgh Steelers quarterback Ben Roethlisberger, he is the last man standing among his 2004 draft class, but that doesn’t mean the NFL won’t try and get every last ounce out of the ‘Ben Roethlisberger is a bad leader’ story by bringing back old teammates and asking them about Roethlisberger.
