I remember his time in postgame interviews that he seemed to struggle, but maybe there was more to the story.
Found this article from Rickie's last year in the league with the Rays.

From the article, a quote about his work before he was drafted, "When Cador first met Weeks, he noticed a speech impediment, a stutter. Cador knew big things were ahead for Weeks — “lots and lots of interviews’’ — so he quietly arranged for a speech therapist to work with Weeks. No one ever knew."
Also, some quotes from Rays personnel that talks to Rickie' ability to talk with other players.
“But when Rickie says something, we listen,’’ Rays pitcher Alex Cobb said. “He knows how to act like a pro. We respect him so much. Nobody has to say it. It’s just the truth.’’
“He just has the ability to capture a room,’’ Cobb said. “Not everyone can do that. Some people try and it falls flat. Not him. I think everyone is aware of who he is.’’
