Bassmaster University is on Saturday at the Choctaw Casino event center, but watching Greg Hackney fish is like going to school. He’s flippin into brush and when he comes to an area he believes holds fish, he will cover every square inch. It’s almost like he’s got a grid in his head and wants to get his bait into every quadrant. Hackney is so fluid and natural with his flippin it’s almost like he does this for a living. Wait, he does. His bait spends very little time out of the water.
