This reminds me a lot of 2017, with Karlsson suffering what should have been a season ending injury so close to the start of the playoffs.
I understand it is not completely apples to apples, since Brady's original injury was sustained a the 4NF, then he suffered a different (apparently not as serious) injury.
He is going to go 150 percent, injured or not, and it will be glorious. Just enjoy the show.
