ESPN’s Mike Reiss believes “there is potential for significant improvement in the deep passing game” for the Patriots this season. It appears Reiss bases this opinion primarily on how the deep-passing game has looked in early workouts. There’s certainly room for improvement. QB Mac Jones ranked just 26th among 31 qualifiers in deep-ball completion rate, according to ESPN Stats. He checked in above-average in on-target rate on downfield passes. In addition to more experience for the young QB and another off-season with his pass-catchers, New England added WR DeVante Parker via trade and speedy WR Tyquan Thornton in the 2nd round of the draft. Increasing his deep-ball production would be especially valuable for Jones, because he lacks rushing production and New England doesn’t figure to be a high-volume passing offense
