A few things on this..
1) Didn't Duke say he wanted to spend his whole career as a Brown? The league is still leaning towards a RBBC/2&1 combo. He is a great pass catcher. I would love to see what he could do as a 2-down back, but even he has to know he's not a ground & pounder. Hyde is most likely a 1-year guy. Chubb will be replacing the Crow/Hyde roll as the 1-2 down guy. Pound the ball. He caught 31 passes in HIS WHOLE COLLEGE CAREER. I think Duke is safe to get a ton of action.
2) If we are bitching about Dukey's playing time because we may have too crowded of an offense, that is a situation we have not been in since when...? That is fantastic fucking news. Also, Hue may have the intelligence/attention span of my damn puppy, but Haley, Dorsey and the other FO has to know the importance of Duke in our offense as a 2-RB set, all pass catching plays, etc. So, he should and will be seeing the ball. Plus the dude has averaged over 4ypc the past 2 years, so it's not like he's a damn slouch carrying the ball.
3) Going back to Dorsey/Haley, they have to be dumb not to try and actually get that contract done. Especially w/Haley coming from probably the best RB in the NFL who is great at catching the ball, he has to know the value of bringing back Dukey. If he is asking for an absurd amount of $, then okay, hold off. But even if it is slightly above market for him, get it done and lock him up. We can pound Chubb (giggity) and use Duke in many roles for the next 4 years.
