Holmgren is one of the highest up on the Bill Walsh tree because he was the QB coach during the last Walsh championship year in 1988 and the OC during the following 1989 championship season under Seifert. Bill Walsh did not have OCs so the highest ranking offensive coach during his era was the QB coach. Holmgren is the direct disciple of the Genius.
Almost all of these coaches have strong relationships with those above them on the tree meaning they were OCs/DCs ... Mike McCarthy who was brought into coaching by Paul Hackett at the University of Pittsburg was not an OC under Hackett however.... McCarthy worked with Montana in KC as Quality Control in 1993/1994 and also as QB Coach with Steve Bono & Grbac from 95-97 when Paul Hackett was OC at KC from 93-97.
Also note I don't believe Jim Fassel should be listed under the Walsh tree. They are acquaintances but that's about it. Also note Jim Harbaugh's link is not that strong with Gruden's branch. Bill Callahan was the OC under Gruden and Harbaugh was mainly Quality Control guy for two years.. he was QB Coach, but not for Gannon. Callahan did the coaching for Gannon.
Bottomline: Superbowls Grow on Trees...
