Decent completion rate More TDs than INTs (just), and YPA a bit above Gabbert Zone... there’s probably a number of worse QBs who have had a season as a starter.
The aforementioned Clipboard Jesus (aka Charlie Whitehurst) made 9 starts in an 11-year career, 5 of them in one season for the Titans. A pretty dismal 55% completion rate from 396 attempts and 6.2 YPA, though only 8 INTs and 11 TDs.
Peterman by comparison has thrown 12 INTs including three pick-sixes from 135 attempts Rodgers has the same number of pick-sixes from 7,332 attempts including play-offs
