Mat Hoffman is not easily wowed.

As the man who took BMX freestyle to new heights, he has soared in many ways during the past four decades. He has set records for big air, including going 25-plus feet above a 30-foot ramp. He has created skills that many tricksters who followed after him won't even attempt, including two-and-a-half turns in the air without his hands on the bike's handlebars.

It's hard to amaze this guy.

But ask Hoffman about being selected for induction into the Oklahoma Sports Hall of Fame, and you can hear the astonishment in his voice.
