You could... but I think you're risking a guy with an inconsistent workload for a guy who hasn't been producing with a full workload. Generally speaking, I side with the guy that I know is going to get the rock over the guy who blows up occasionally. That being said, if Stewart is like RB4 on your roster, I'm totally fine with taking the upside guy in Duke. I think ultimately though, Stewart will get it together, barring injury.
