He has now been named a first team All-American by all five national media organizations recognized by the NCAA this year in determining consensus All-Americans.
The other four honors came from the AFCA (American Football Coaches Association), the FWAA (Football Writers Association of America), The Sporting News and the Walter Camp Foundation. Barron was also a consensus All-American in 2003.
"Alex has been one of our more consistent blockers in the years he has started for Florida State," said head coach Bobby Bowden.
"He has been blessed with phenomenal athletic ability and puts it to good use. We're proud of his accomplishments and he deserves the honor."
Barron becomes the seventh two-time consensus All-American in Florida State history and the first offensive lineman.
Barron joins Ron Simmons, Deion Sanders, Marvin Jones, Derrick Brooks, Sebastian Janikowski and Peter Warrick in the elite group. He will be the ninth Seminole to have his locker sealed, joining those six players along with Heisman Trophy winners Charlie Ward and Chris Weinke.
"It's an honor and a great accomplishment, especially here at Florida State," said Barron.
"Just to be considered among Florida State players like Deion Sanders, Marvin Jones, Derrick Brooks and Chris Weinke is a great feeling. With all of the great offensive linemen who have played at Florida State, it's hard to believe I am the first two-time consensus All-American. I feel very blessed."
Barron, an Outland Trophy finalist, put together an excellent senior year. He allowed just one sack during the 11-game regular season, did not grade out below 87% in a single game, and had an average season grade of 91%. Barron is considered to be the top offensive line prospect for the 2005 NFL Draft.
Also recognized by the Associated Press on Monday was senior defensive tackle Travis Johnson, who was named to the third team. Johnson led all ACC defensive linemen with 17.0 tackles for loss this season and ranks third all-time at Florida State with 41.5 tackles behind the line of scrimmage.
