Jamarcus through 31 games: 7 wins, 18 touchdowns, 23 interceptions, 34.3% success rate, 6 yards per attempt, 4.83 net yards per pass attempt, 9.3% sack percentage
Zach through 32 games: 11 wins, 21 touchdowns, 25 interceptions, 36.8% success rate, 6.3 yards per attempt, 4.95 net yards per attempt, 9.7% sack percentage
Zach Wilson has thrown 946 passes, JaMarcus threw 680 (Jamarcus barely played in his first season and was benched in his third season)
Out of curiosity, I looked up the stats of our own epic bust of a QB, and Dwayne Haskins was on pace to be worse than both these guys.
