USF strength and conditioning coach Hans Straub has resigned after sending a tweet over the weekend criticizing former Bulls defensive end and San Francisco 49ers fifth-round draft pick Aaron Lynch.
"Thought an organization with 5 Super Bowl titles would have a stricter draft criteria. Clearly, integrity & character are not a priority," Straub posted to his personal Twitter account Saturday.
The tweet was deleted, but Straub was nonetheless placed on indefinite leave before USF announced his resignation Tuesday afternoon.
"USF Athletics has high expectations for each and every student-athlete, coach and staff member," Bulls athletic director Mark Harlan said in a statement. "To that end, I have accepted the resignation of Hans Straub from the position of head strength and conditioning coach. I thank him for his contributions to USF Athletics and wish him well in his future endeavors. A national search for his replacement will begin immediately."
Lynch was named an All-American at Notre Dame in 2011, but sat out 2012 after transferring to USF and finished with six sacks in 2013. Though he still earned first-team All-AAC honors in his lone season in Tampa, his draft stock slipped.
"I am a first-round talent," Lynch said after the draft. "[But] I've made some mistakes in my past and I figured that's what hurt me a little bit."
Lynch was recommended to the 49ers and Jim Harbaugh by Bulls coach Willie Taggart, who played for Harbaugh's father Jack at Western Kentucky.
