CW Jr, in addition to being the son of an actual coach who worked in the both the pros and college, has worked for Belichick, Saban, Kiffen, and Sarkisian before becoming an OC and now works for Jeff Scott, ex-OC of Clemson.
McVay, in addition to being the grandson of a college and pro head coach as well as the GM of 5 Super Bowl teams, worked for Jon Gruden, Mike Shanahan and Jay Gruden before he became OC.
Rees, in addition to being the son of a scout/ player development guy (not a coach), has 1 year at NW under Mick McCall who is now the RB coach at ISU and 1 year at SD under Ken Whisenhunt. and 4 years under Kelly as a coach and 4 years as a player. Oh.... I wouldn't want to forget his 7 day stint as a qb in the pros.
So explain to me how Rees's high level football knowledge compares to CW Jr and McVay.
