Roux is easily one of our best options at RB. That isn't even debatable, honestly. He's not perfect by any means, but I think the way he plays suits the formation perfectly.
He's doing all right for CCM right now, he's their captain.
Fitzgerald is our best RB but as he'll never play for us Roux is the next cab off the rank. I also think he's continually improving and is still quite young remember.
