Mitch Trubisky has no need to prepare for a game in the coming weeks after the Bears’ season sputtered to a close with a 23-10 loss to the Vikings at U.S. Bank Stadium on Sunday. He will have no head coach or offensive coordinator for a period of time after the Bears fire John Fox and Dowell Loggains. But the quarterback plans to study anyway, starting with an examination of how he can be better in the red zone. Two of the Bears’ final three drives of Trubisky’s rookie season ended with them giving up the ball on downs in the red zone. Trubisky threw four straight incomplete passes from the 6-yard line midway through the fourth quarter. And from the 2 on the last drive, he threw a pass for no gain and an incompletion, then flipped to Tarik Cohen, who was taken down at the 1 on fourth down. The last of Trubisky’s 12 starts went much like his season as a whole — some good but plenty to pick apart. “You always find out from each game what you did well and what you need to work on, so I am going to go back through all of the games and continue to look at those things,” Trubisky said. “I got more comfortable as the weeks went on to play my game, be a leader of this team and help our offense grow and get better. … The defense did a great job today keeping us in there, but we have to find ways to score in the red zone to have a better chance of winning.” Trubisky finished his day 20-for-36 for 178 yards, no touchdowns and no turnovers. He passed Kyle Orton for the top spot among Bears rookies with 196 completions. Trubisky finished with 2,193 yards — another Bears rookie record — seven touchdown passes and seven interceptions.
