GREENSBORO, N.C. -- Its a football Saturday at the Atlantic Coast Conference headquarters, and Michael Strickland sits in a windowless room scanning a wall of flat-panel televisions and monitors on a nearby table.The ACCs senior associate commissioner for football operations and two replay officials are closely watching a pair of league games. They confer with officials at each stadium to ensure any ruling on a sideline catch, dive for the pylon or fumble is the correct call, part of a season-long experiment by the ACC -- as well as the Southeastern and Pac-12 conferences -- with collaborative instant replay that has off-site officials assist on reviews.Strickland describes it as a safety net with a simple goal: get it right.Our view, Strickland said, is that two sets of eyes are probably better than just one.The ACC and SEC are using collaborative replay for all games at league stadiums, including at independent Notre Dame as an ACC member in other sports. These review centers operate in a supporting role out of the ACC headquarters in Greensboro, North Carolina, and the SEC offices in Birmingham, Alabama.The Pac-12 uses it on a limited basis. Spokesman Dave Hirsch said replay officials at California and Oregon can communicate with the leagues San Francisco headquarters.The Big Ten is studying the idea but hasnt implemented it.The ACC and SEC will report findings to the NCAA rules committee in the offseason. SEC coordinator of officials Steve Shaw called it an absolute success so far and Strickland said it has cut the number of plays that mightve gone the other way.Data from both leagues show the added scrutiny was catching more errors. The ACCs rate of calls reversed on review is up from about 24 percent last season to 29 percent through last weekends games, while the SEC was up from about 37 percent to 41 percent. The average review times -- roughly 90 seconds for both -- are up slightly.Theres so much in fairness to players, coaches and fans, ACC Commissioner John Swofford said. Theres a lot riding on these games. What you always want is, at the end of the day, a game had been fairly won or lost.Swofford said the league spent about $500,000 in upgrades to an existing gameday operations center for collaborative replay. The ACC recently allowed an Associated Press reporter inside to spend about 45 minutes observing how it works.Replay officials can turn a dial to conduct their own frame-by frame evaluation on monitors at their seats within seconds and talk to a stadium replay official via headset if something requires a closer look. They watch games carried via online stream to minimize delays.The days first stoppage reviewed whether a called fumble shouldve been an incompletion or if the receiver was down before the ball came out. Replay official Ralph Pickett ran footage back and forth, and it didnt take long to confirm a clear fumble while conferring with the stadium official.I agree, I agree, he said into the headset. Play quickly resumed, illustrating how the burden still rests largely with stadium officials.Once we get the game stopped, we collaborate and we come to the right answer, Shaw said. But we still are dependent on that replay official inside the stadium to stop the game. Thats his primary role.At times, you could get a collaborative discussion with him from the video center in Birmingham, `Hey, you need to stop this game. But in our up-tempo world today, really the guy in-stadium has got to make the decision to stop it.Still, it cant prevent every mistake.During North Carolinas win at Miami last month, replay officials never saw the angle that could have overturned a first-quarter touchdown catch by the Tar Heels in the 20-13 win. Footage focused on Austin Proehls right foot landing inbounds but the ESPN production crew didnt send angles showing Proehl bobble the ball while falling out of bounds.Regardless, no one has to sell Duke coach David Cutcliffe on steps to reduce the chances of an officiating mistake.His Blue Devils lost to Miami last year on an eight-lateral kickoff return for a final-play touchdown that shouldnt have counted. The ACC later suspended officials for two games for botching calls on the field and during review.I like the idea because you know theres an extra set of eyes and theyre seeing it immediately, Cutcliffe said. And they can buzz the box and say, `Whoa, wait a minute here, lets look at this.---AP Sports Writers Joedy McCreary in Durham, North Carolina, and John Zenor in Montgomery, Alabama, contributed to this report.---Follow Aaron Beard on Twitter at http://www.twitter.com/aaronbeardap---More AP college football at http://collegefootball.ap.org and http://www.twitter.com/APTop-25 Cheap Baseball Rangers Jerseys .H. -- Matt Kenseth made it 2 for 2 in the Chase, holding off teammate Kyle Busch to win Sunday at New Hampshire Motor Speedway.
