There were questions about Aaron Lynch’s commitment and work ethic when the 49ers selected him in the fifth round in 2014, and they’ve persisted in the NFL. In October, after he served a season-opening, four-game suspension for violating the NFL’s drug policy, the 49ers outside linebacker revealed that he lost about 30 pounds during his break. Lynch said he was hovering around 300 pounds in training camp before his diet. Is Lynch, who has missed the past five games with a high ankle sprain, still learning how to be a pro? Moments after the 49ers drafted Lynch, his strength and conditioning coach at South Florida, Hans Straub, disparaged the selection: “Clearly, integrity & character are not a priority,” Straub said on Twitter before he was fired for posting the message. Two years later, Lynch didn’t appear to report to training camp in great shape, although Kelly suggested otherwise today. “For a guy that was going to sit for four games, I thought he was in -- I mean he passed our conditioning test with no problem,” Kelly said.
