Here’s a quote from Chicago Tribune article Thursday, Jan 21, 1999 which was a day after it was announced he was leaving for Colorado. It says he sent a message to players “that week” that he was staying which couldn’t have been more than 2 days before he left (right now I can’t find a story saying exactly when the message to the players was sent). Obviously he would have interviewed and negotiated by the time he was sending that email to the players.
“For example, his players cited a mass e-mail from Barnett this week, assuring them that he wasn’t going to Colorado. Imagine their surprise when they awoke to find “Gary’s Gone” splashed in bold type across the front page of Wednesday’s Daily Northwestern.
“To tell you the truth, it made a lot of people lose respect for him because of the e-mail and what was said,” sophomore running back Brian Marshall said. “He gave us his word. When anybody goes back on his word, you lose respect for him. How can you trust him?””
