Martinez because he is much more dynamic.
Gotta give Rattler his props, though. He was really good at sliding around in the pocket, avoiding pressure, and buying time for receivers to get open. He's no 2AM when he tucks and runs but he did chunk us in the 4th quarter setting OU up at about the 3yd line for what turned out to be the winning TD.
SR is good, but I'll take our guy every day, and with our O-line, we NEED our guy.
