By passer rating, yesterday was his 13th best game out of 35 starts. Only counting this year, 4th out of 8.5.
By rushing yards, 15th out of 35. Only counting this year, 4th out of 8 (not counting the half for counting stats)
By passing yards (223), 7th out of 35. Only counting this year, 3rd out of 8 (not counting the half for counting stats)
By AY/A, 12th out of 35. Only counting this year, 4th out of 8.5.
Even if I accept the notion that no games he played in before this season counted, it's much closer to his median (top half in all those categories) than his floor.
