Some of Nitschke's worst days, and the Packers in general back then were spent chasing Tarkenton. Nowadays, half the teams have Tarkenton-types. Point being: I don't want somebody like Bullough when we face Kaepernick, Wilson, or Griffin. I want somebody like Shazier at ILB. That is compounded by the fact the Packer ILBs have a lot of coverage responsibilities.
