Based on 2016 ESPN Splits:
on 3rd (or 4th) with 3 or more yards to go:
56/106 for 746 Yards, 7.04 YPA, 7 TDs, 1 INT, 21 Runs for 165 Yards (7.86 YPC) and 3 more TDs
with 9+ yards to go:
26/45 for 421, 9.36 YPA, 1 TD, 1 INT, 9 Runs for 86 Yards (9.6 YPC)
Take that for what you will. Bad completion %, but solid YPA is what I see in those situations.
EDIT: Also, 10 TDs on 127 combined attempts comes out to 7.87% TD% - which seems pretty good.
