Despite the fact that Morris was an unheralded and largely unknown sixth-round prospect out of Florida Atlantic University, we perhaps should have at least considered the notion that he could become a 1,000-yard back as a rookie.
After all, his head coach, Mike Shanahan, has a history of unearthing surprise standouts in the backfield that includes previous 1,000-yard rushers such as Olandis Gary and Mike Anderson (Anderson, like Morris, was a sixth-rounder who rushed for more than 1,000 yards as a rookie).
The secret behind the success of Shanahan running backs is rooted in players with some level of talent, of course, but the system Shanahan has used as a foundation of his offenses lends itself to successful running backs, as well. His zone-blocking scheme up front puts a premium on athletic linemen with decisive backs rushing behind them (the same system Gary Kubiak, a Shanahan disciple, has used to help catapult Arian Foster to fantasy stardom in Houston).
Point is, production is the byproduct of system and talent, and a player miscast within a system can be hindered. This can make or break fantasy seasons.
Let's examine 10 players who will benefit from playing in a new system in 2013, boosting their fantasy value.
