Schonert has struggled to make an impact with any of the offenses he's coached.
While 2008 in Buffalo was his only year as an offensive coordinator, Schonert has been the quarterbacks coach for 13 seasons with five clubs. In 1992, Schonert headed to Tampa Bay where he "guided" Vinny Testaverde to 14 touchdowns and 16 interceptions and a ticket out of Tampa. The Bucs were 5-11, but Turk stayed, with a young quarterback under his tutelage. Miami's Craig Erickson skippered Tampa to a 11-18 record over two years, but did show improvement before being booted in favor of Trent Dilfer. Dilfer tossed four touchdowns to go with 18 interceptions under Schonert, who was removed from his post and headed North.
Schonert's greatest success came in Buffalo from 1998-2000, where he couldn't choose between two quarterbacks with successful numbers. The Bills were 29-19 during that time, with Doug Flutie (47 TD, 30 INT) and Rob Johnson (22 TD, 10 INT) co-existing peacefully. He left after an 8-8 campaign in Orchard Park.
Schonert had another inexperienced starter in Carolina in 2001. Chris Weinke went 1-14 as a starter, with 11 TD and 19 INT. Turk's tenure in Carolina ended there. He took a year off in 2002 before returning to the league in 2003 with the Giants, where he coached Kerry Collins to one of his worst years as a professional. Collins and Schonert were out of jobs. After another year off, Schonert spent a season with the Saints, ensuring the end of Aaron Brooks' time in New Orleans. Three wins and 13 losses tend to correspond with 13 touchdowns and 17 interceptions. Schonert, Brooks, gone.
Sensing a pattern here? Schonert has failed with rookies, veterans, Pro Bowlers and Super Bowlers.
