It wasn't one player over and over. Logan is gone, Stafford will be in better game situations with hopefully starting WRs running the correct routes, LeShoure and Bell and Pettgirew and Calvin had 3, 2, 2, and 3 respectively, losing every single one of them. That kind of bad luck just won't happen again. You replay 2012 with the same team, they don't have 33 turnovers. They are talented and can protect the ball 10 more times or at least recovery some fumbles they lose. The 2010 squad had 25 turnovers, 2011 23. Pettgirew has never lost a fumble before in his career, Calvin has never lost 3, LeShoure and Bell won't losee 100% of hte balls they put on the ground plus they have Bush if you don't like LeShoure's 3 fumble lost ball security for 200 carries.
Read this and then get back to me with a better attitude.
