The San Francisco 49ers outside linebacker aced it.
"A couple of guys made some comments," the svelte-looking Smith said Thursday, ahead of the squad's first practice. "I hit this offseason really hard."
Smith, who has not had a normal spring and summer off of the field, did his best to prepare for the 2014 campaign on it. He said he changed up his workouts, with an emphasis on improving his power and technique.
How exactly does a pass-rusher with 42 sacks in his first three NFL seasons get better?
"All around," Smith said. "I'm far from reaching the top, so I have some climbing to improve.
"I'm in the best shape I've been in I'm coming into a camp. My mind is in the best spot it's been in, so I'm feeling great."
Before Smith spoke, Jim Harbaugh told reporters he was glad to see that Smith was holding himself accountable for his mistakes.
"This process is a growing process," Smith said, "and I'm in a better spot than I have been."
Smith, who also said that he has maintained his sobriety, confirmed that he will meet with NFL commissioner Roger Goodell in the near future.
"My team supports me a lot," he said. "It's good to be back on the field, doing something I love and being around my teammates."
