Is 'bad luck' a euphemism for 'aging'? Because that's what Russell and Rodgers have done to where injuries and poor performance get you. Having an old QB fail to play well or last a full season is not bad luck, it's bad planning.
At some point teams have to at least ease up if not stop cooking, otherwise the weight of the dead cap hits prevents your team from signing or keeping (good) players. If GB hadn't hit the jackpot on its receivers this past season, or if Gute hadn't drafted Jordan Love, they would've been a trainwreck last year...and they had kicked everything they could forward just to get under the cap and absorb Rodgers cap hit.
