But after a serious struggle in the BYU game and a dropped pass on a sure TD throw from Landry Jones in the Idaho State game Tennell found himself on the bench struggling to get any meaningful minutes.
Over the past two weeks he has hauled in four receptions for 69 yards and a score, and looked very smooth in doing so.
So could the once highly talked up receiver be putting himself in a spot to receive more action?
"He is to a degree," OU head coach Bob Stoops answered when asked if Tennell is getting back in the mix. "It was good to see him make some positive plays and some competitive plays."
OU quarterback Landry Jones also feels comfortable with an experienced receiver on the field, who can go out and make plays on the ball.
"Adron is one of those guys who is just a real long strider and he is going to get separation just because of his speed and height and his jumping ability," Jones said of Tennell's talents.
"He is super-athletic and obviously you guys know that and everyone knows that. I think Adron has a real knack for getting open and he is going to be a really good player for us."
