I don't understand the idea that questioning whether this was Brandon's or Hoke's call is somehow implying that Hoke is dumb. Hoke has a different perspective than the rest of us, may have been fairly insulated from the criticism, and may have placed more value on loyalty and "family atmosphere" of the coaching staff than did Brandon. There's a hundred reasons why Hoke may not have wanted to make a change that have nothing to do with him being dumb. Many think keeping Borges would have been a dumb move, but that doesn't remotely mean anyone thinks Hoke is actually dumb.
We had insiders saying up until the moment this was announced that Hoke wasn't going to make any changes. It's not unreasonable to conclude from that talk and every public statement Hoke made all year that a change wouldn't be made without Brandon stepping in. I don't understand why it's so offensive to wonder if that's what ultimately happened.
