To be fair though, most (myself included) who are of the opinion that Butch was always going to go with those he was familiar with and felt could run his system on offense first and foremost don't really see the defensive hires as related.
The Shoop hire proved that Butch is willing to delegate and go outside his comfort zone on defense. On offense, the only hire he has to suggest otherwise is Scott (the first time around at least).
Some point to Gillespie, and it's true he had no history with Butch. But it's also true that he came from the same coaching tree as Butch (Holgerson).
It is true we don't know for sure. It's also true that Butch doesn't have that much of a history of going outside his comfort zone on offense.
Either way, he's ultimately seen offensive improvement and success, somyou cant really argue too vehemently against the guys he's decided on in the past.
