Gophers defensive players wear maroon jerseys in practice; the offensive guys don white -- except quarterbacks, who wear gold, no-contact jerseys.
But unlike preseasons past, no players have worn brown or pink.
When coach Jerry Kill took over the Gophers football program before the 2011 season, the coach immediately cracked down on players who got into trouble, skipped class or showed up late to team meetings.
To change the culture, Kill made offenders wear brown or pink shirts that read, "Minnesota Loafers" and "I let my teammates down."
Senior running back Rodrick Williams was once a regular member of that doghouse for being tardy.
