To believe that means believing if the Brewers called around with a package including some of Pena, Adamczewski, Frias, Ragsdale, Gasser, Jett, Fischer, Payne, Hardin, etc. that there was literally no one interested in surrendering the equivalent of Hope, an A+ arm a year from the Rule 5, and a 28 year old "prospect" SP.
The fact that the deal was completed days before the deadline just gives extra credence to the idea that if the Tigers were interested in dealing with another team they could have done so.
