"I think he was the best defensive coach that I've played for professionally," cornerback Jabari Greer told WPRT-FM in Nashville on Tuesday, per TitanInsider.com.
"Gregg did a great job of creating a professional approach to football," Greer said. "He made us accountable to each other. He really created something that we still live off of today in our defensive room. We play with a passion and we play with an intensity that is going to be unmatched."
Greer's not alone in his admiration for Williams; we've seen countless Saints players line up to defend both him and coach Sean Payton. Titans players aren't far behind. Tennessee cornerback Alterraun Verner gushed over Williams in June, saying: "He's hitting the ground running. He's trying to get us back to where we need to be."
And from safety Michael Griffin: "I'm just very excited to see what he can do with this team."
Williams remains stationed below embattled defensive coordinator Jerry Gray in the Titans' pecking order, but that's easy to forget. One season removed from banishment, Williams' return to the sideline remains one of the more intriguing coaching subplots of 2013.
