Not sure what all you're looking for...
From my perspective, Jeff Byers is one of the treasures of Penn State Wrestling. He has the knack of making a listener feel like they are right there, on top of the action. It's a gift that I can't explain, but those that have listened to him understand.
Jeff started announcing Penn State Wrestling in 1990, following Dean DeVore, and has been at the mic ever since. Something says they shared duties for a couple years, I can't remember the exact arrangement, but do remember listening to both (I go back to 1973, when starting to follow Penn State).
"Ironhead" came from his younger days, and is somehow related to Craig "Ironhead" Heyward. He is also affectionately called "The Voice of Penn State Wrestling", or as Coach Cael simply states, "The Voice".
