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)
The big difference is that Jamarcus was before the rookie salary cap, so he was more damaging to his team financially.
