NFL rookies come into the league with high hopes and high expectations. Until they take the field, every first-rounder is a perennial pro-bowler while each second and third can become a day one starter.
The truth generally comes up something short of expectation, that is especially true when additional factors add up to boost those expectations beyond the ordinary pressures afforded a rookie.
How many will fold under that pressure and how many will rise to meet it? That cannot be answered until the season has come and gone. In the meantime all we can do is identify who they are, and wonder just how they'll do.
