Define tools to succeed. Does we have the tools to be a truly elite QB (Rogers, Brady) in this league? Not sure yet. The physical tools are thete though.
But does he need to be that elite QB for the Bears to succeed as a team? No, he doesn't. He just has to be good enough. And i think he will be that. Call them excuses if you want, but he was a green QB coming in, and is on his 2nd offensive system in 2 seasons already. With almost no preseason time, I dont see how any even halfway reasonable fan could have expected him to play lights out in game 1, especially it being at Lambeau under the lights.
If he is still playing close to the same at the end of this season...then we worry. Might see Chase in the game if it continues half the season though...
