When did he make that promise?
I would have never made that promise, but I never heard that, either. He said he is making a little commitment to ErMarr, and is clearly making a commitment to Sweetney and maybe even Frank Williams. I don't remember him even mentioning Vin Baker. I don't see where he has the room to do this.
