At that point, you move on. We don’t even know yet if there is a mess to drag anyone in to.
It’s interesting that Roenicke is already implicated, and according to some, these scandals clearly involve upper management and ownership, which should implicate Tek. But going outside (where you really don’t know what the guy was doing) is how the Sox got into this mess.
Just promote Roenicke and move on. He’s been around the league and even managed teams before without any cheating scandals...
