Maryland (1-4 overall, 0-2 Atlantic Coast Conference) will meet No. 17 Georgia Tech (3-1, 2-1) today at 4 p.m. in Byrd Stadium.
"He makes a lot of good decisions for them and throws well, but he becomes very dangerous when he scrambles," said Duffner. "When he does, that's when the big plays start to fall for them. They can score, and score very quickly.
"I've seen him on film against Maryland in the past, and he has made some unbelievable plays."
In the past five years, Maryland has had trouble containing scrambling quarterbacks like Jones because the Terps have lacked speed on the perimeter. Against West Virginia earlier this season, Maryland blew a 19-point lead in the fourth quarter as Mountaineers option quarterback Darren Studstill repeatedly beat the Terps with rollout passes and his scrambling.
Studstill, who started only the second half, led fourth-quarter touchdown drives of 78, 73 and 55 yards. He completed 14 of 21 passes for 166 yards with touchdown passes of 10, 6 and 20 yards to rally the Mountaineers to a 34-33 victory.
Jones has completed 80 of 140 passes for 924 yards and six touchdowns this season. Until a week ago in a 16-13 win over N.C. State, Jones had thrown 122 passes without an interception.
"I'm very concerned about our people on the perimeter, especially after what Studstill did to us," said
Duffner. "His pressure on those people can create a lot of problems."
Here's a brief history of Jones against Maryland:
*In 1989, Jones, then a redshirt freshman, completed 16 of 23 passes for 209 yards and four touchdowns as Georgia Tech defeated Maryland, 28-24, to end a 17-game conference losing streak. Georgia Tech went unbeaten in its next 19 games.
*In 1990, Jones completed 15 of 25 passes for 271 yards, including a 40-yard touchdown, as Georgia Tech routed Maryland, 31-3, on its way to a share of the national title.
*In 1991, Jones played with a virus but still completed 10 of 21 passes for 227 yards and three touchdowns. He completed a bomb of 82 yards as Georgia Tech crushed Maryland, 34-10.
"Plain and simple, we stop Jones we stop most of their offense," said Mike Jarmolowich, Maryland's senior inside linebacker.
Maybe use a "spy," the same way some NFL teams use linebackers to shadow Philadelphia Eagles quarterback Randall Cunningham? Or spread out the defensive ends and outside linebackers to keep Jones in the pocket?
"We have some things we're working on, and that's as much as I'll tell," said Duffner, whose defense is allowing 433.6 yards per game.
