Offer No. 4 is in for John Tyler cornerback Isaac Warren.

Northwestern State has joined three fellow FCS schools in Grambling State, Sam Houston State and Tennessee State for Warren's services, according to Lions head coach Ricklan Holmes. 

Warren (6-1, 187) has shown quite a bit of college potential through spring practices. He's an excellent player in man coverage, frequently jamming receivers to the degree they can't  shed him to resume their routes.

The corner also has good closing speed and great awareness in zone coverage.

Northwestern State finished last season with a 3-4 Southland Conference record and was 6-6 overall with two of those losses coming against Cincinnati and UAB.

It finished the year with the 65th-best defense out of 122 FCS schools, an average of 389 yards against per game.

The program is headed by second-year coach Jay Thomas. He took Nicholls State to the Division I-AA playoffs in 2005 as its head and coached two All-American defensive backs during his time in Thibodaux, La., prior to his firing in 2009. He immediately became associate head coach at Northwestern State from 2010 to 2011 and coached the Demon's defensive line before becoming defensive coordinator of Missouri Southern on the Division II level for the 2012 season.

Northwestern State has a history of scheduling a major FBS opponent and then a FBS opponent outside the power conferences. This year's trips include Baylor and Louisiana Tech.

Warren has until Feb. 4, 2015, to field scholarship opportunities and sign with a college football program.
