There are General Managers in the NFL who have worked under Ted Thompson. John Schneider 7 - 2, Reggie McKenzie 7 - 2, John Dorsey 7 - 3 and if you want to count Thompon's time at Seattle, Scot McCloughan 6 - 3 - 1
That's 21 wins vs 7 losses or if you add Scot 27 - 10 - 1.
The common thread is those General Managers draft well and are plugging holes via free agency and/or trade.
Packers do not have the defense they have, but the Broncos canned their head coach and got to the Super Bowl and won the following year.
