TAMPA — Three days after issuing a disparaging tweet about former Bulls defensive end Aaron Lynch, USF strength and conditioning coach Hans Straub resigned.
Josh Newberg of 247Sports first reported Tuesday morning Straub had been suspended indefinitely. Late Tuesday afternoon, the school confirmed the resignation. Straub didn't return a text message.
"USF Athletics has high expectations for each and every student-athlete, coach and staff member," athletic director Mark Harlan said in a statement released by the school. "To that end, I have accepted the resignation of Hans Straub from the position of head strength and conditioning coach. … A national search for his replacement will begin immediately."
Straub, entering his second year at USF, issued a tweet shortly after the 49ers drafted Lynch in the fifth round Saturday:
Thought an organization with 5 Super Bowl titles would have a stricter draft criteria. Clearly, integrity & character are not a priority
The tweet has since been removed. Speaking on the American Athletic Conference coaches spring teleconference Tuesday morning, coach Willie Taggart said USF's administration was handling the matter.
"First off I would like to say I am so proud and so happy for Aaron Lynch being drafted by the 49ers," Taggart said. "Very disappointed in the tweet. Hans knows how disappointed I am, Mark (Harlan) knows how disappointed I am, our football team knows how disappointed I am."
Lynch, a Notre Dame transfer, played one season at USF. He led the Bulls in sacks (six) and earned first-team all-conference honors, but struggled with consistency and composure. San Francisco signed Lynch on Tuesday.
Niners coach Jim Harbaugh told NFL Network that Taggart vouched for Lynch. "I think from a character standpoint, Aaron wasn't any different than any other kid, and he worked really hard," Taggart said.
