​EDITOR’S NOTE: This is the second installment in a series breaking down each position ahead of the opening of Buffalo Bills training camp July 29.ORCHARD PARK — Quarterbacks tend to make bad decisions when they have been hit enough times. There’s one decision to make on the way to the turf for a sack: don’t let go of the ball.AdvertisementAdvertisementAdvertisementSeems simple enough, right?But putting quarterbacks on the ground before the ball was thrown wasn’t a high priority during the Sean McDermott era. Instead, his defense focused on confusing quarterbacks, making them think longer than preferred and banking on them making a bad decision.The Bills ranked in the top-10 in takeaways eight times in nine seasons under McDermott, including five in the top-five. They ranked in the top-10 in sacks once during that span.It worked for the Bills during the regular season, ranking in the top-five five times in pass defense. But in the playoffs, it’s much harder to fool good quarterbacks and it showed in their inability to create pressure and make quarterbacks uncomfortable.AdvertisementAdvertisementAdvertisementIn the AFC divisional round, Denver quarterback Bo Nix was the only playoff quarterback in the last 25 years to attempt 45 passes, complete fewer than 60% of them and not get sacked. In McDermott’s playoff wins, the Bills had a 42.8% pressure rate, compared to 25.8% in losses, with average for last year’s playoff winners being 36.8%.Enter defensive coordinator Jim Leonhard, whose blitz-happy scheme is as hyper-aggressive as McDermott’s was when he first arrived in Buffalo. And the man charged with flipping Buffalo’s edge rushers from watchmen to predators is his former co-defensive coordinator at Wisconsin, Bobby April III.The last time April coached for the Bills, the expectations were through the roof. He was the outside linebackers coach for Rex Ryan in 2015 and 2016, but the pass rush fell flat.After getting fired with the rest of Ryan’s staff, April spent a year out of football and has since spent his time in college, most recently as Stanford’s defensive coordinator.AdvertisementAdvertisementAdvertisementApril has coached big-time college edge rushers like Eagles linebacker Zack Baun, Pittsburgh’s Nate Herbig and the Jets’ No. 2 overall pick David Bailey. But now he must apply it to the NFL.“I took everything I was teaching the NFL player to the college level,” April told GNN Sports. “I felt like I was using the tools that I was using with grown men initially. … Luckily we had success. We had good kids too that bought in. … And that’s really the NFL, just having guys buying and believing what you do.”April is tasked with elevating 2021 first-round pick Greg Rousseau, who was good enough to net a four-year, $80 million extension, but still hasn’t logged more than eight sacks in a season. April has already said the Bills intend to unleash Rousseau rather than forcing him to set the edge all the ti
