Re: The kicking game. You don't bring in an UDFA Rookie kicker and expect there not to be some bumps in the road. He's missed 2 40+ FGs. Will he be a great kicker? I have no idea, but IMO you don't bring in him to give up on him quickly. In college, he converted FGs at a 79% rate. Not overwhelmingly great, but I couldn't find any data on what distance his misses were from. As for the Commanders kicker, I wouldn't use his 7 FG day to annoint him as the latest great kicker found on the scrap heap just yet. He's been around for a while and was available for a reason. Good kickers aren't just sitting around at home doing nothing. Career 18/25 40-49, 2/6 50+, missed 5 PAT's his rookie year. 10 times out of 10 you take the rookie the Packers have over him, and hope he realizes his upside.
As for Willis.. I agree he's not a NFL quality starter. I'd like to have someone better as a back up. Who? At what cost? There aren't 32 NFL quality starters in the league right now IMO, so to have a back up available who you are confident can be that is a luxury few teams have. Who has a guy on the bench that you believe right now can step in and take at team on a playoff run? Indy has a guy that I believe could in Flacco, but not for that team.. IMO you can't expect to have a back up that you can win many games with. You hope you have a guy that can go 1-1, 1-2, 2-3 in a short stretch as a starter and not cost you a playoff opportunity. It's RARE to have an MVP candidate in Carson Wentz and have Nick Foles as your back up who takes you on a playoff run and wins the Super Bowl MVP. That just doesn't happen very often and to expect that kind of performance from a back up isn't realistic. The reality is, if Love missing significant time, playoff hopes are slim, and I don't know of an option for back up QB that changes that. I'm not sure if he was out for 8-10 weeks and they signed Tannehill who appears to be the best available longer term option if THAT changes anything.
Run defense.. key to their run defense for a while has been to get the lead and take their offense out of the run game for the most part. For me, it's no different now. Offense get the lead, defense hold against a team forced to pass more. Back up QB might cause some challenges there.
