Baldinger has a right to state his opinion; nevertheless that's all it is and doesn't bear any more truth than if one of us were to make the same statements. Many of those in his position feel the need to make bold predictions for whatever reason -- oftentimes to validate their so-called expertise.
I do find him knowledgable but certainly not psychic. We'll see in due time whether the Cowboys have regrets for their RB decisions being what they presently are. I don't think it's beyond probability for them to introduce a RB onto their practice squad at some point. It's always possible that one of the regulars could get seriously injured or cut. It happens all the time.
