In theory, the NFL stock market shouldn't change much this close to the draft itself.
By now, teams have mostly solidified boards with grades for each prospect after going through the paces of a lengthy offseason, spanning film study, interviews, the combine, workouts and more. And truthfully, the work of the scouting department began months before the NFL season even ended, as front offices always have a year-round eye on the future.
But to say stock market changes don't happen at all this late in the process would be a blatant fib. News always breaks and alters the outlook.
