A color-coded glance at practice. Come back later for a trip down the catwalk with the coaches.

Offensive players (Mark Rodgers with the ball, fellow freshman Jordan Roberts trying to take it) wear white. Freshman have tape on their helmets that serve as labels. This prevents “Hey … you. Come here.”

Defensive players (sizable freshman D.J. Shaw on the left, senior Doug Slavonic on the right) wear blue. This makes things less confusing when the offense goes against the defense. But what happens when offensive players mesh with defensive players in special teams drills?

The side about to get possession — field goal block, punt/kick return — puts orange caps on the helmets.

Players in red jerseys can’t practice. You should see how much Ryan Stanchek hates this. I’m guessing he’s going to be somewhat intense if he returns to practice Thursday.

Players in green jerseys can practice and do many drills, but guys like Reed Williams are withheld from contact.

A gold jersey means you’re a quarterback and not to be messed with lest you face the consequences. Safety Quinton Andrews famously ignored that rule as a freshman one day and a riot nearly ensued.
