Understanding UNC's offense

In balanced formations, the quarterback may also flip the play to the other side. Other times, against specific defensive looks, the bubble may be switched to a "Smoke Screen," where the outside receiver steps back at the snap to receive the pass while the slot blocks—this was the variation that led to the winning score against Virginia in 2012. The shift from the pitch to the quick screen (bubble or smoke) as the outside "third" option provides an additional benefit in that it's one of the few examples where a forward pass involves significantly less risk than a running play since a botched bubble screen is simply an incomplete pass, while a botched pitch on the option is a potential turnover.
