Introvert, or whatever, seeing how Macdonald's Ravens defenses fly around and make plays, and seem to anticipate whatever the opposing offense is trying to do--THAT is impressive schitt. To me, that speaks to a coach who teaches and motivates, has 1000% buy-in from his players, scouts opponents well, and has great schemes he excels at teaching. No more Seahawks soft-zone give away first downs crap. And did I mention yet how Macdonald's defense stuffed the 49ers and Lions vaunted offenses this year? Also Macdonald's defenses have on-the-field leaders, like the LOB did back in the day. Roquan Smith comes to mind.
I loved how Pete Carroll established the Seahawks culture, getting the team to play hard for EACH OTHER, LOB = Love Our Brothers. Also loved Pete's "always compete" approach, and setting up practices around that concept. It doesn't really matter whether you're an introvert or extrovert, good coaching ideas work, and either style can implement them effectively. Mike Macdonald, as an introvert, doesn't have to replicate Pete Carroll's cheerleader "syntax". He'll find others to step in and fill the parts where extrovert skills are needed.
Yes, organizational leadership skills will no doubt be part of where Macdonald needs work. He's got Schneider to help, and even Pete Carroll possibly as an advisor.
ASIDE--OLD SCHOOL COACHING PHILOSOPHY "BAD OLD DAYS"

Kids who played youth sports in 70s, anyone remember all the abusive Vince Lombardi wannabe coaches? They copied Vince Lombardi's gruff "drill instructor" "syntax", without realizing Lombardi was successful often DESPITE that syntax. The Lombardi wannabe's I had as coaches SUCKED, crappy teachers, rigid egomaniac narcissists, and typically had worse W/L success than non-abusive coaches. I celebrate Pete Carroll for being the anti-Lombardi.
