He's ranked 1st in Comp % (removing all players that have like 30 or less attempts - likely non QBs)
19th in total QBR
76th in passing yards
Tied 43rd in TDs (10 others)
98th in attempts
That's a pretty good QB ranking across the board and a bit nit picky to complain about 4 picks in 170 attempts (about 2%).
