Walsh was a finalist for the Lou Groza Award as a junior but missed 14 of 35 kicks last season. That has not affected his draft preparation, he said.
"I just want to continue to hit the ball the way I have been hitting it the last month and a half and the way I have trained myself to hit it my entire career," he said.
Walsh will kick between 12 and 15 field goals from varying distances and angles, he said. He doesn't think he has to perfect to impress, he added.
"I don't think you can have that pressure when you kick field goals," he said. "You have to go out there and be confident in what you do and be confident in your abilities because your abilities are what got you here at this point."
Walsh patterns his game after Chicago place-kicker Robbie Gould, he said.
