8. Rex Grossman
Just seeing Rex Grossman on this list is going to give plenty of fans an anxiety attack. Grossman was a walking, talking turnover waiting to happen. The guy gave Bears fans too many headaches, was the reason many of them lost a lot of hair and, quite frankly, is a big reason why it's still hard to see any Bears player wear the number 8.
But, at the same time, Grossman was good enough to start at quarterback for a Super Bowl team, and he deserves to be mentioned in this conversation. Back in 2003, Grossman was drafted by the Bears in the first round at no. 22 overall out of Florida. He ended up only playing one real, full season for the team as the starter.
Yet, we're talking about the Bears, here. So, of course a guy like that makes an all-time list such as this.
In that lone season Grossman started all 16 games, he threw for 3,193 yards, 23 touchdowns and 20 interceptions. He also led the NFL in turnovers, as a whole, with 29 total between picks and lost fumbles. Any time the guy got hit, every fan had the same thought: "Fumble."
Grossman ended his Bears career throwing for 6,164 yards, 33 touchdowns and 35 interceptions.
