Imagine how easy it would have been for Fox to say no. But the coach didn't, saying in so many words that the Bears now will give Trubisky a chance to supplant Glennon. Maybe Trubisky will do so Sunday if Glennon posts another microscopic passer rating and the rookie steals the show again. Maybe it will take a few regular-season games for the Bears to reach the conclusion that Trubisky simultaneously can develop and give his team its best chance of winning on Sundays. Maybe it never happens because Glennon got a wake-up call and responded.
