I don't trust McDaniels, not in the slightest!
He became head coach in Denver and by all accounts his ego completely took over... how he could make anyone good. Forcing them to draft Tebow (while a great guy, is no NFL starting QB).
Then promising he'd become the Colts head coach... completely backing out...
For McDaniels there needs to be a checks and balance... someone to keep him in line... Bill Belichick does that... I'm not sure the Packers have that guy to keep him in check.
I much rather just go with Mike Pettine as head coach... the defense is doing a fine job! And as Browns head coach he hired a GREAT OC (who's now 49ers head coach).
Only problem was they drafted Johnny Football and the team GM/President/Owners/someone, forced them to play Johnny Football against the coaches wills... so the GREAT OC quit!
But not forcing them, Pettine might be able to do a good job.
