From the video

JJ McCarthy... The prince who was promised... the highlight reel was nuts from that game... Disgusting throws... he only played five quarters this year... he's more Jameis than Jamus where a lot of turnover worthy throws, but a lot of really impressive big time throws... it's also kind of like undeal for fantasy that he's he's losing goal line snaps for Jamus... when he comes out of the buy, he gets Philly, he gets Washington... he gets the Colts in week 12, a banged up San Francisco team week 13, then Cleveland week 15, Detroit week 16, Dallas week 17 in the fantasy football championship. Absolutely. He's a Btier at least.
STACKED’s take
Elite arm talent in five quarters; B-tier post-bye with soft schedule.
JJ McCarthy's recent performance was elite-level despite playing only five quarters all season. His highlight reel was described as 'disgusting,' with throws that would rank in Caleb Williams' top three career games. The source notes his play style features both turnover-worthy throws and impressive big-time throws, and his top-five throws would rank top-three among all quarterbacks this year. However, he is losing goal-line snaps to Jameis Winston, who is handling QB sneaks exclusively, representing a downside to McCarthy's fantasy ceiling in short-yardage situations. Post-bye schedule features favorable matchups: Philadelphia, Washington, Indianapolis (Week 12), banged-up San Francisco (Week 13), Cleveland (Week 15), Detroit (Week 16), and Dallas (Week 17 championship). The source ranks him B-tier minimum out of bye, with conviction that he will be available in every league after the bye and represents better value than holding other QB2s; projected to move to A-tier after bye week.
