There are numerous former Illinois football players scattered throughout the NFL, and they are suiting up in the preseason right now.
It seems like in every preseason game, you will find an Illini on either side of the ball. Tommy DeVito is over there throwing the ball around for the New York Giants. Devon Witherspoon is shutting down wide receivers for the Seattle Seahawks. Pat Bryant is catching passes with the Denver Broncos.
I could go on and on, but you get the point. There are a lot of Illinois players in the NFL.
