Your QB hasn't fully developed his accuracy yet (77/100), so once that hits all red, the INT might decrease some, but if I were you, I'd look to improve the skill guys around Allison. Everybody uses speed on defense, and your slow WR probably struggle to get open.
Your lack of running game doesn't help either. You run the ball less than anyone, so defenses are likely ignoring the run, selling out to stop the pass.
I would suggest you look to add speed at RB/WR, even if the other skills are lacking.
