Two N.F.L. draft prospects sat on a couch on the shaded patio outside a hotel room in St. Petersburg, Fla. They were waiting to take another test. They had only been in town a couple of days, and already this was their sixth test. Each time it was the same routine: Go to this room at this time, ask for this person, do whatever he tells you. No one said what the tests were for, and so far the prospects had never been told how they did.
The day was a snowbird special for midwinter Florida: hot but not too hot, humid but not too humid.
