In all seriousness, I think it behooves us to remember that Shepard was fired not by Scott Harris and the Tigers, but by Bally Sports Detroit, who have different imperatives than the Tigers when it comes to their end of the business. The front office may or may not have input into the decision, but the decision rests solely with BSD. Whether the new announcer is a baseball cognoscente is probably beside the point—it's pretty likely that all BSD cares about is that the new announcer represents and sells the product in the most audience-pleasing way possible.
I gotta believe the only reason Shepard was fired all all was probably the same reason Avila was fired, or maybe even why Jeimer was let go: the public outcry around him rose to such an elevated level that the castle could not ignore the pitchforks and the torches any longer. I think it's likely that the feedback they were getting was that Gibson and Maybin and Monroe are great, but Shepard was pretty awful. So it's entirely possible they will find someone in the Shepard mold, and that might well be Greg Gania from Erie as some here prefer, or maybe even Dan Hasty from West Michigan as some here don't. But I think I would be surprised to see them steal away a Dan Orsillo- or Joe Davis-level talent for the Tigers. I honestly believe the viewers don't require or even care about that level of quality. If they did care, they would have wanted to run Gibson and C-Mo out of the booth years ago.
