It's a short week for the Giants, and Manning trusts Larry Donnell, evidenced by Donnell's consistent target totals through Week 3: eight, nine, and six.
Donnell caught 18 of those 23 targets (a 72.3% catch rate), while averaging 6.0 receptions for 45.6 yards. That's a 96-catch rate for 729.6 yards over 16 games. He'll slow down eventually, but it's hard to think Manning will look elsewhere on a short week after Donnell went a perfect six-for-six on targets this week against the Texans, the Giants' first win of the year.
