The 2011-2013 Washington Redskins

2011: -14 turnover differential, 5-11 record
2012: +17 turnover differential, 10-6 record
2013: -8 turnover differential, 3-13 record

Changes in Turnover Differential: +31, -25
Changes in Win Total: +5, -7

Perhaps the most interesting case study when looking at turnovers and win/loss records is the Washington Redskins over the past three seasons. Between 2011 and 2012 they managed a positive turnaround similar to those in KC and Philly last season, but to their dismay they suffered a drop off similar to those of Houston and Detroit between 2012-2013. The Washington defense was certainly partly responsible, but once again most of the blame falls at the feet of the head coach and QB. In 2011 the Washington QBs (led by Rex Grossman) threw a combined 19 interceptions. RGIII was then drafted and had a fantastic rookie season where he only threw five interceptions in his 15 starts. This past season RGIII and Kirk Cousins combined to throw 19 interceptions, matching the number thrown two years prior. Basically, the Redskins of 2013 reverted back to the Redskins of 2011. Shanahan is now gone and Washington is hoping a new coaching staff can help RGIII recapture his rookie success.
