Covid screwed his entire offseason over last year, one of the reasons it took him so long to even land on a team due to recovering from his surgery and not being able to go to teams for physicals.
Then he signs onto one of the more difficult to learn schemes.
The Patriots have always struggled against dual threat qbs, and it seemed pretty clear during the few games I watched last year that they didn't have an understanding of how to use one on offense either. A lot times it seemed like they treated him like a wildcat qb, no real RPO misdirects, just qb draws and run options.
The talent around him also sucked.
So yea, I do expect him to play better this year with a full off season, don't think it will be MVP caliber, but will the coaching evolve to take advantage of his skill set this year? Who knows.
