John Fox has said a lot of stupid things since becoming coach of the Bears — and inexplicably remaining coach of the Bears — but here’s the dumbest, and I don’t know if anything is even second: When asked Sunday why he didn’t let the 49ers score to make it 19-14 with more than 90 seconds remaining in order to get the ball back with time to march down the field and score the deciding TD, Fox said “We felt good about the block we had for a potential field goal.’’ Let’s review: The Bears had blocked precisely one field goal all season, Robbie Gould had kicked four field goals already Sunday, the Bears hadn’t blocked any attempt, and the field-goal try the Bears insane head coach felt so good about blocking would be the shortest of the day for the kicker who used to work for Fox and the Bears and was familiar with the vagaries of Soldier Field to the point that he’s the franchise’s leading scorer. So, for those of you scoring at home, Fox is willing to give a faceless special team more opportunity with a miniscule attempt to accomplish the task than a potential franchise quarterback who is the only thing that matters this season and especially this month. You could argue that Trubisky has been a bad bet to convert potential game-winning drives. That doesn’t matter. You could scream that offensive coordinator Dowell Loggains gets a front-row seat in the team picture of worst playcallers in the NFL. That’s doesn’t matter, either. No, what matters is that whatever the obstacles, both on his side of the field and the other, Trubisky gets as many hero chances as possible because those are what define franchise quarterbacks, and besides, he would’ve had a game-winning drive two weeks earlier if Fox’s choice to replace Gould was an actual NFL kicker.
