If that's true, perhaps being shown the respect he deserves from the Rams will help change that feeling.I don't think he is a Ram at heart so no. He was certainly good enough as a player to be worthy though.
I don't think he holds any grudges over the circumstances of his leaving, but I do think it's natural he's going to be more loyal to his more recent team, just as Faulk considers himself more than a Ram than a Colt.
Dickerson might be an exception to this theory though.
