The Pittsburgh Steelers selected Le'Veon Bell with the 48th overall pick in the 2013 NFL Draft ahead of Eddie Lacy.
Lacy has established himself as one of the NFL's best backs with 1,028 yards and a 4.1 yards per carry average.
Bell is averaging 3.3 yards per carry for the Steelers.
"An easy one," said Tomlin on choosing Bell over Lacy. The Steelers love offensive versatility.
