Sorry, but for me it isn't hindsight and the bolded is the whole thing. Lou, and most fans, took results from absurd and (hopefully) once in a lifetime circumstances and convinced himself that he had a great team on his hands. He didn't. Not even close.
As for McCrimmon, I'm not sure either, but I think it's a pretty safe bet that the team wouldn't look the same and for me, that would be a huge plus. I am so sick looking at this same core and their same plain vanilla style and results.
And please, spare us all any more of the "Trotz only comes here for Lou" nonsense because that's what it is. If you want to give Lou credit for hiring him, fine, but speculating that BT wouldn't have come here for anyone else is just that, speculation, with no basis in fact whatsoever.
