My theory.........
I think CJ wants to be treated like a "star" but he's not at that level for a RB.
In reality, CJ came to the Rams at a perfect time. The team was rolling, OLINE was solid, team was heading to the playoffs, and CJ had some VERY NICE holes to run through. He gets that body going North/South and he's a load to bring down.
But, he's not the "ELITE" RB he thinks he is and he thinks he "DESERVES" things that other elite RB's are getting.
Just my thoughts because there's something going on.........
