'Big Brother' -- Taps Ex-Texas A&M Football Player ... With Abs

The next "Big Brother" HoH could be a guy from A&M ... 'cause one of the contestants is a former Aggies football player -- who also happens to have a pretty insane physique.

The ex-football player is 23-year-old Clay Honeycutt -- a former defensive back for Texas A&M who graduated in 2014.

We spoke with Clay's dad Lynn -- who also played for the Aggies -- and he told us he thinks Clay's football background will give him an edge on the competition.

"There's a wide diversity of people in the cast and football will help him because he has always gotten along with different groups of people. He's had all kinds of different roommates, so I think that will help him."

One of those people was Johnny Manziel ... who played at A&M from 2011 to 2013.
