After the college football season, potential draftees are training their asses off for the NFL Combine and all the subsequent Pro Day and private workouts. They’ll get interviewed on who their best friend was in 4th grade and whether their mothers are prostitutes they can handle an NFL playbook. They’ll have every nook and cranny of their body measured like they’re a prized farm animal.
They’ll run the proverbial gamut, all to find out that the hardest thing of all comes after they get drafted: they have to somehow swim in the NFL.
Most of them, as you know, will disappear from the NFL worldview never to be heard from again - most of them sooner rather than later.
