It sucks for us, but it's a big gamble by GB, because it puts everyone on the clock. They are Superbowl or bust for the next couple years, and I'm not sure they are a clear favorite in the NFC after this trade. Everything is going to ride on Jordan Love.
Losing Kenny Clark figures to hurt the middle of their defense, potentially leaving them more vulnerable against the run. Parsons himself is not a good run defense. He'll make them better, but how much? This defense isn't stacked like the 2018 Bears. He probably had a more talented defense last year with the Cowboys than he's walking into with GB.
Again, it will all hinge on how good Love is. If he can replicate his success at the end of 2 seasons ago, they're definite SB contenders, but if he looks more like he did this past year, I don't see them as a serious threat to PHI, DET, or even WAS.
