I'd expect them to go back to last year's production levels, 2nd half of season, where Kamara was pulling about 23 ppg and Ingram about 19. 30+ per game was unsustainable.
Yeah Kamara was never going to sustain that anyway. You should get 20/25 out of him per week with Ingram in the mix. They are two completely different backs, so game script will determine the usage.
