The defense needs to be significantly improved. APRH (meaning 3-4 starters aren't lost for most of the season), they better be in the top 10 defenses, especially if BG brings in say a top FA pass rusher.
Packers need to be competitive in the NFC Championship game to protect Stubby - that's what I'd tell Murphy if I were BG. I will get him the players, but he'd better produce.
