One of the big changes was moving defensive tackle, Verdis Brown, back to the offensive line. Brown played a lot on the offensive line in high school but came into the Illinois program as a defensive tackle. The Illini needed more depth on the offensive line, though. It is still to-be-determined if Brown will stay on the offensive line, according to Erich Fisher of Rivals.
I, actually, liked this move by the Illini. The offensive line needs more help this season than the defensive line. Illinois has done a great job recruiting defensive tackles, but come 2020, they are going to need a little more depth because of some departing players.
