5. Mitchell Trubisky
Oh, boy. For those who had to live through the height of the "Mitchell Trubisky over Patrick Mahomes" period, you might want to look away.
But, the fact is, Trubisky indeed lines up right here with exactly where he sits on the team's all-time passing leaderboard. He is currently fifth all-time in passing yards with 10,609, which is just a shade over Kramer's career numbers with the Bears, and in one less season.
So, in a sick and twisted way, that's fairly impressive. For a little while, there, we thought Trubisky might have been able to be "that guy" for the Bears. He wasn't drafted no. 2 overall for no reason, right?
Well, don't answer that question, actually. There is plenty to be said about why Trubisky was a bust, but again, we're talking about the Bears, here. It doesn't take much to make a leaderboard as a Chicago quarterback, and for that reason, Trubisky comes in right here at number five.
