Asked why he withdrew from the team last year, Lewis said, "Because I didn't like a lot of things." Refusing to single anyone out, Lewis said he was frustrated by how some players didn't properly study, work out and communicate.
"Everything reverts back to losing, one way or another," he said. "If that's going wrong off the field, what makes you think it's going to click when we step on the field?"
The tumultuous 6-10 regular season spilled over to the spring, when Lewis criticized the team's defensive scheme and not-so-massive defensive tackles on national TV.
Lewis has since apologized to his teammates for his comments.
"I go through frustrations," Lewis said. "I make mistakes. I'm not inhuman."
