The world is a better place because of Paul’s passion, commitment, and selflessness. His legacy will live on forever.
So sad to hear about the passing of @Seahawks owner Paul Allen. In my 4 years in Sea he treated me, my teammates & the coaches w/great honor & respect. The Hawks treat their players as well or better than any organization because of him. My prayers go out to his family.— Trent Dilfer (@DilfersDimes) October 15, 2018

Remember Paul Allen at NFL owners meetings. Richest man in the room (by far), wearing jeans and an untucked flannel shirt, sitting back studying and observing. And when he spoke -- albeit rarely -- it was pure wisdom.— Andrew Brandt (@AndrewBrandt) October 15, 2018
Saddened and stunned by the passing of Paul Allen. A giant who was as humble and generous as they come, and so respected as a fellow NFL owner. Rest in peace, Paul.— Jim Irsay (@JimIrsay) October 15, 2018
