"He did some great things in this league," Cowboys owner Jerry Jones said. "But it's a high bar when you have to do things that aren't necessarily agreed upon by a lot of people. I am disappointed that he's not sitting up here with me tonight."
"It's hard to gauge if these were his decisions or decisions that were made by owners,Taylor Gabriel Falcons Jersey," Nowinski said. "But those were the decisions of that era. It's a black eye on the era,Cheap NFL Jerseys China, and on the people who were in charge."
