Rams beat writer Nick Wagoner on rookie Tre Mason: "I expect Mason to be nipping at the heels of (Zac Stacy) for carries and handle the No. 2 role. I also wouldn't be surprised if he usurped Stacy at some point, especially if Stacy struggles with nagging injuries again."
We'd be surprised if Mason overtakes Stacy, who was impressive for the Rams in 2013. He may have trouble beating out Benny Cunningham as Stacy's backup.
