The Patriots' quarterback situation is in as much turmoil as it's been all season after Mac Jones was benched for Bailey Zappe at halftime in Week 12, and New England threw another spanner in the works by bringing Grier on board ahead of Week 13. It's unclear what coach Bill Belichick's plans are at quarterback for the home stretch of the season, but it's difficult at this point to imagine Grier would prove a significant downgrade from Jones (4.2 yards per attempt in Week 12) or Zappe (3.9 yards per attempt in Week 12).
New England signed Grier to its active roster off the Bengals' practice squad in September. He has since been available for depth under center behind Mac Jones and Bailey Zappe, but his services were never called for. The 28-year-old has not seen the field for regular-season action since 2019 in Carolina, and he is now set to look for a new opportunity. One possibility is landing on the Pats' practice squad, assuming he clears waivers.
