I would go as far as to day that they actually managed to "destroy" it instead of improving it. First time in F1 history that this is done to such an extend. Pathetic really. Of course, now that Lauda has joined we will witness a majestic collapse, squad resuffle, people getting fired etc. early signs point to this at least.
Don't get me wrong, I am a Merc fan, just this team from Brackley doesn't have anything that screams "Mercedes" on it.
