I am just one man over here trying to get through as many college football prospects as possible. I usually am able to average about one prospect per day for each weekday between the Super Bowl and the Draft which puts me roughly at 55-60 players by the time draft comes.
That number of prospects generally seems like it is enough (at least my bosses think so), as the majority of draft spectators lose some interest by the time the 3rd round comes around - save for a few famous names from the area colleges who are not quite at the top tier of the gold.
