Long before Chicago Bears wide receiver Allen Robinson was a valuable weapon in Matt Nagy's innovative offense, another NFL head coach prepared him for the pro game.

Bill O'Brien of the Houston Texans coached Robinson while serving as Penn State's head coach from 2012 to 2013.

"I learned a lot. A big part was the X's and O's," Robinson said at his Evening Within Reach fundraising event, which raised money to help provide educational resources for low-income students. "He had a lot of experience in the NFL."

Before coaching Penn State, O'Brien was an offensive assistant, wide receivers coach, quarterbacks coach and offensive coordinator for the New England Patriots. Using his background on a Super Bowl team coached by Bill Belichick, he implemented a pro-style offense at Penn State.

Playing in a sophisticated college scheme gave Robinson an edge after the Jacksonville Jaguars selected him 61st overall in the 2014 NFL Draft.

"A lot of these college systems don't translate over to the NFL," he said. "So being able to have him as a college coach and being able to learn the game inside and out really has been very beneficial."

Penn State remains a part of Robinson -- literally. He has a large tattoo on his torso, commemorating his 36-yard reception against Michigan, which set up the game-tying score late in a quadruple-overtime, 43-40 Nittany Lions win.

He also remains close with his former Penn State roommate and teammate, Bears safety Adrian Amos, who helped welcome him to Chicago.

Robinson hasn't spoken to O'Brien in a while, but when he played on the Jaguars, they faced their AFC South foe, the Texans, twice a season, giving Robinson a chance to catch up before the game with the coach who helped mold him.

"It was always exciting," Robinson said. "He coached me when I was 17, 18-years old."
