The Rams Zac Stacy must rise to challenge once again

Zac Stacy made his mark as a fifth-round pick last year, falling just shy of 1,000 yards.

Now, the running back must prove his worth all over again.

The St. Louis Rams sent a message in this year's draft, taking Heisman Trophy finalist Tre Mason in the third round.

And though they've released Daryl Richardson, undrafted rookie Benny Cunningham was impressive last season and former second-rounder Isaiah Pead remains in the mix.

There's always going to be someone gunning for the job.

Stacy has the advantage heading into training camp because he knows the routine, has a better grasp of the playbook and knows firsthand about the pounding that must be absorbed.
