The No Fly Zone is back at Tulane.

The Green Wave has only completed three spring football practices, but junior cornerback Lorenzo Doss - whose seven interceptions led Tulane in 2013 - and junior safety Darion Monroe are ready to wreak havoc again after two stellar seasons at Tulane. And that tenacity to the football starts now against Tulane's three quarterbacks in the wide-open competition.

“In the secondary we play fast – we have a saying, ‘No Fly Zone,'" Doss said. "We don’t give up the deep ball or intermediate routes, anything like that.

"Our quarterbacks are a tough group of competitors. They’re gonna push us and we know it. They make throws that sometimes we can’t get to. We’re all bettering each other and keep improving each day.”

Reaching the R&L Carriers New Orleans Bowl this past December, the program's first bowl game since 2002, wasn't enough for the defense. Doss said it was a great achievement, but now they want more.

Monroe added that the defense's greater veteran presence improves communication as preparations for 2014 are under way. Twelve more spring football practices remain.

"We're deep back there now, and we can play quicker," Monroe said. "We learned (communication) last year that helped us take that next step forward and be a better team.... We try to pick with the quarterbacks every now and then; they need the competition, so we show them different looks. (Senior Nick Montana) is older, so he’s seen it all basically, but Tanner (Lee), we show him all kinds of things. He’s learning now."

Tulane coach Curtis Johnson praised the quarterbacks after Monday's practice - Montana, Lee, a redshirt freshman, and redshirt sophomore Devin Powell. Johnson said they protected the football much better, and still the Tulane defense is "hitting it off," especially on the defensive line.

"The quarterbacks threw it around a little bit better; (Lee) looked good again," Johnson said. "I don’t think the quarterbacks threw any (interceptions) today. That’s refreshing and pleasing. Sometimes when you’re putting a lot of offense in, you’re gonna expect some stuff to happen. I really want those guys to compete and compete hard."
