Since then Maryland has released him to all schools including Vanderbilt, but they also filed a complaint against Vandy with the ACC, which the conference passed on to the SEC.
Other schools that O'Brien has been connected to include Washington, Wisconsin, Michigan State, Stanford, Arizona, South Florida, and Mississippi.
A native of Kemersville, N.C., O'Brien is 6-3, 215 pounds and his list of target schools includes many that lost senior quarterbacks last season. O'Brien missed several games last season when he broke his non-throwing arm, but in his career he has completed 342 of 603 passes for 4,086 yards and 29 touchdowns with 18 interceptions.
In his standout 2010 season he completed 192 of 337 passes for 2,438 yards and 22 touchdowns with just eight interceptions.
Because he redshirted his first year of college and is graduating this May after just three years, O'Brien will have two years of eligibility and would be available for the 2012 season.
Again, Oklahoma State has been contacted by O'Brien and the Cowboys are at least under consideration by the transfer quarterback.
