Over the previous two seasons Reggie Bush caught 81 passes from Drew Brees out of the backfield. In his first year in New Orleans, Bush's replacement, Darren Sproles, had 86 receptions. It's easy to see why Brees trusts Sproles—he does more with his chances. The former Charger averaged about two more yards per catch this year than Bush did in '09--10, and he has a knack for finding the first-down marker. It will be intriguing to see how teams cover Sproles. Would the Niners use a quick inside 'backer like NaVorro Bowman or bring a safety like Dashon Goldson? Whoever is on him, Sproles will be a matchup nightmare, as he has been all year.
