Shawnee offensive lineman Creed Humphrey committed to Texas A&M on Wednesday.
Later that night, Oklahoma assistant head coach Cale Gundy sent out a tweet that seemed directed Humphrey's way.

"Piece of advice to recruits. It's real simple. Schools are winning championships or talking about winning championships. Do your homework," Gundy tweeted.
Humphrey chose the Aggies over a collection of offers that included Oklahoma, Oklahoma State, Texas, Alabama, Virginia Tech and Houston among others.
Gundy hasn't been shy about posting his opinions on Twitter.
Two years ago, when several SEC coaches pushed for a rule that would've forced offenses to wait 10 seconds to snap the ball after the play clock started, Gundy chimed in after the proposal was withdrawn.
