According to Highland Park High School head coach Randy Allen, that's the sound a football makes as it goes through the air when Matthew throws it. Allen talks about that and more in a recent interview with Kirk Dooley of Neighborsgo.com. Allen recounted his once-in-a-lifetime trip to New York City for the NFL Draft, and how he first saw Matthew playing in the middle of the street when Matthew was a child. It's a candid story worth reading.
Here are some photos of Matthew and Coach Allen through the years.
