Mitch Trubisky went from eventual starter to the Chicago Bears‘ best quarterback in a matter of hours Thursday.

Entering the game without very high expectations, as Mike Glennon was named the Bears starter weeks ago, the second overall pick had a very impressive preseason debut – particularly compared to his competition.

QB Completions Attempts Compl. % Yards TDs INTs
Trubisky 18 25 72% 166 1 0
Glennon 2 8 25% 20 0 1

Glennon threw a pick-6 on the first series of the game, lost a fumble on a botched snap, and finished with a 0.0 passer rating, while Trubisky started by completing his first seven pass attempts and leading the game in passing yards against the Denver Broncos. Trubisky also out-rushed Glennon with 38 yards on three attempts, while the veteran had one rush for no yards.

Having started training camp as the third-string quarterback, Trubisky is making up ground on Glennon in a hurry. However, after the game Bears coach John Fox said that his quarterback depth chart would not be altered despite the play of Trubisky.

“Our depth chart is not going to change after one game,” Fox said, according to ESPN’s Jeff Dickerson. “That’s a really good defense our first unit went against, probably one of the top three defenses in the league. You have to look at a lot of different things. I can understand how you guys might think (we could make a change), but we’re not going to change a whole lot after one game.”
