NFL: Top 15 All-Time Passing Yard Leaders Still Playing

9. Tony Romo - 33,270

The Cowboys are such an unknown quantity ahead of 2015, after an off-season which saw them secure Dez Bryant but let DeMarco Murray run all the way to Philadelphia to join Chip Kelly's masterplan. There's been swirling rumours about whether the Cowboys will opt for the controversial RB Adrian Peterson who is ready for a return to the NFL, though as things stand Bryant will be the main weapon of choice, with Tony Romo licking his lips at the prospect. Romo's back continues to generate stories, but he'll be hoping for another step in the right direction with the Cowboys.
