Daniel Jones out there in Indianapolis. Torn Achilles after, you know, a phenomenal start to the season... he's not going to want to take off like he used to when he was younger, at least in the first half of the season... he's not going to have as much mobility and and as much rushing yards as he has in the past. Um, and which is going to significantly hurt his value at least from a fantasy perspective.
STACKED’s take
Torn Achilles will limit mobility early season; rushing production expected to decline materially.
Daniel Jones suffered a torn Achilles, a rare injury for starting quarterbacks (only six in NFL history dating back to Marino). Unlike older quarterbacks like Aaron Rodgers and Kirk Cousins who suffered the same injury, Jones is young and mobile, which creates a unique concern: the Achilles won't be ready for full explosiveness early in recovery, preventing him from being as elusive as he normally would be. The source expects Jones to avoid taking off like he did when younger, at least in the first half of the season. This significantly reduces his rushing yards and fantasy value. The Colts' investment in Jones suggests they believe the injury won't severely interrupt his performance, but the source expects him to be a low-end QB2 dependent on passing volume rather than dual-threat upside.
