"I'll be extremely confident in those guys," Mayfield said Wednesday. "Obviously, I had rapport with Trey going back to last year, Sterling for years obviously, and Jalen, all of offseason and training camp. I expect those guys to have success and play really well, and you know, throughout the week, getting on the same page within the game plan as we continue to nail this thing down. We expect everybody to step up in a big way and [we're] still leaning on our offensive line -- [I] thought they played great."
