Here is a stat that is often overlooked when comparing QB's.
Tony Romo's FUMBLES
2006 - fumbled 9 times lost 3 - goes with 13 picks (16 turnovers) (10 games)
2007 - fumbled 10 times lost 2 - goes with 19 picks (21 turnovers) (16 games)
2008 - fumbled 13 times lost 7 - goes with 14 picks (21 turnovers) (13 games)
Romo - 58 turnovers in 39 games started
Jay Cutler's fumbles
2006 - fumbled 8 times lost 2 - goes with 5 picks ( 7 turnovers) (5 games)
2007 - fumbled 11 times lost 4 - goes with 14 picks (18 turnovers) (16 games)
2008 - fumbled 5 times lost 2 - goes with 18 picks (20 turnovers) (16 games)
Cutler - 45 turnovers in 37 games started
Romo blows Cutler away on TD passes, but I would say 2 things about this.
1. TD passes are not necessarily an indication of the overall effectiveness of an offense. Brett Favre blew Aikman away on TD passes but Dallas had the better offensive production in the time that those teams were both at their best in the 90's. It is SOME indication of a QB's effectiveness, but it can also simply reflect a team's philosophy inside the redzone.
2. If you believe that playoff football and big games are more determined by turnovers than anything else, then it is obvious that Romo has a ball protection issue that he has to cure. 58 turnovers in 39 games equals 1 and half turnovers (roughly) for every game that Romo has started. Just for perspective, Aikman's total turnovers for his career, which includes the 1989 drubbing he had to endure, and his final year which wasn't his normal level of play, totaled LESS than the games he played in. (I think it was 163-165) Remember, that includes
1989 - 9 TD's 18 Int's
1990 - 11 TD's 18 Int's
and his last year 2000 - 7 TD's 14 Int's 2 fumbles lost
1991 - 10 total turnovers
1992 - 14 total turnovers
1993 - 9
1994 - 14
1995 - 9
1996 - 19
1997 - 16
1998 - 6
1999 - 14
THE LAST TWO YEARS BY ROMO (21 TURNOVERS) SURPASSES ANY SEASON AIKMAN HAD THROUGHOUT HIS ENTIRE CAREER.
Cutler is 25 years old, Romo is 28 years old. Romo plays on the team with more offensive weapons and a better defense. Romo has been on an NFL roster for 6 years, Cutler for 3 years.
I don't know who I would take, but Romo's turnovers are the only reason it is even a discussion.
