So basically if Chickallo played the same number of snaps, his career stats would look like this: 26 sacks, 9 PD's, 10 FF, 10 FR, 51 QB Hits.
Bud's career stats are 31 sacks, 9 PD's, 6 FF, 3 FR, 50 QB Hits.
For comparison, Watt has played 1,000 less snaps than Dupree and has 3 more career sacks.
Your numbers are skewed. Some of Chicks FFs and FRs are on ST. Take his best season when he started nearly half the year in 16. 2.5 sacks and 2 FFs translates to 4 FFs and 5 sacks. Chick has never been good and took a step back last year when he looked slower, couldn't generate any pressure, and got blown off the line on running plays.
