Has Kamara's Dynamism Spoiled our backfield?

I agree it's almost like coach Peyton felt he needed to to keep forcing the ball to Kamera and eventually things will get back to normal. It was very obvious the guy isn't right and we seem to have much more success overall with Murray. I really like Kamara and I hope he stays with the saints and we don't trade him away like a rumours are saying. But now I'm gonna go gets injured and is no longer effective I don't understand why you don't just let him rest and heal up. At the very least lighten his load a bit but we just kept forcing it to him.
