TAMPA, Fla. — Mark Ingram and Alvin Kamara have already put together the most productive season for any running back tandem in NFL history.

Now, they have a nice round number to go with it. 

Both Ingram and Kamara steamed past 1,500 yards from scrimmage on Sunday against Tampa Bay, the final push past the barrier coming on a 40-yard completion from Drew Brees to Kamara in the third quarter. 

Ingram and Kamara had already passed the most productive duo in NFL history against the Atlanta Falcons on Christmas Eve. In 1985, Cleveland's duo of Earnest Byner (1,462 yards from scrimmage) and Kevin Mack (1,401) set the record. 

Both Browns backs rushed for more than 1,000 yards, while Ingram and Kamara have been much more productive in the passing game.
